User:Thio58167/Fury of the Maelstrom

World of Warcraft: Fury of the Maelstrom (colloquially known as "FotM" or "Fury") is the second World of Warcraft expansion and was officially announced on August 3, 2009 at BlizzCon 2009. Though much of the expansion content takes place in the Great Sea and centers around the plans of the Naga, Deathwing, the Old Gods, and the Burning Legion make several appearances as antagonists throughout the expansion.

Content highlights include the increase of the level cap from 80 to 90, the introduction of the Runemaster Hero class, and new PvP/World PvP content. Like in Wrath of the Lich King, no additional playable races have been added, though many new NPC races were featured.

Opt-ins for the public beta began on July 28th, 2010; the beta began on August 9th. On October 29th, Blizzard announced that Fury of the Maelstrom had gone gold and discs were being manufactured for sale; the game itself was released to the public on November 16, 2010.

Lore
From the official site:

''With the threat of the Scourge destroyed, Azeroth subsides into a brief period of peace. However, the infinite armies of the Elemental Lord, Neptulon, march on the cities of the Horde and Alliance. With all-out war eminent between the two factions, none can know what terrible fates may await under the dark tides of the ever-swirling Maelstrom. Only time will tell if the mortals of this world can set aside their differences and combat the threat... of the tides.''

The Great Sea


The expansion introduced a new "continent" on Azeroth — the many islands and sub-continents of the Great Sea, as opposed to a single continous land mass like Northrend or Kalimdor.

The Great Sea spreads between Kalimdor and the Eastern Kingdoms, and was crossed for the first time in ten thousand years during the Third War. The playable land masses of the Great Sea are essentially equivalent in size to Northrend, with some extraneous islands as well as the later added area of Garok Modan increasing the size further.

Flying mounts can be used in the Great Sea; Players must level to 87 and obtain a Tome of Maritime Flying to unlock this feature. This item is account-bound, so players who have reached level 87 on one character may purchase flight for their lower level characters. Unlike other continents, the Great Sea is not a single, continuous area. Each individual zone, such as Kezan, Gilneas, or Zul'Dazar, is self-contained. Due to the nature of the open ocean, players may not fly from area to area. To alleviate this, boats and zeppelins are used by both factions to great effect, as are portals. Player mages will additionally have access to several new portal spells beyond that of their new capital city, Boralus or Zandalar.

Zones
Continuing a trend from Wrath of the Lich King, Fury of the Maelstrom gives players a choice of three zones to start in, alleviating server load and player frustration on launch day, as well as granting players additional choice in their playstyle. Gilneas, Kul Tiras, and Zul'Dazar all have content for players level 68-72, though Kul Tiras and Zul'Dazar have more questing opportunities for Alliance and Horde players respectively. The Great Sea is designed to allow players to level from level 78 to 90 comfortably. Each of the three starting zones also has a winged dungeon with instances for level 78-82 players respectively - Beigecloud Citadel in Gilneas, Tol Barad in Kul Tias, and Zul'Atai in Zul'Dazar. Horde players access Zul'Dazar via boat from Orgrimmar's Bladefist Harbor to Zandalar; Alliance players can get there by boat to Zin Tyrandi from Auberdine. Kul Tiras can be visited via boat to Boralus from Stormwind Harbor or to Drisburg from the Whispering Shore in Tirisfal Glades.

Zones and their levels:


 * Boralus (Alliance Capital)
 * Zandalar (Horde Capital)
 * Gilneas (78-82)
 * Zul'Dazar (78-82)
 * Kul Tiras (78-82)

 * Shrine of the Primordials (90) (Outdoor PvP)

Areas in Azeroth

 * Acherus: The Ebon Hold and the Scarlet Enclave
 * A new area in the easternmost parts of the Eastern Plaguelands, near Tyr's Hand, which acts as the starting area for death knights.


 * Stormwind Harbor
 * Western Stormwind City has had a new harbor added which provides naval transport to Northrend and to Darkshore, Kalimdor.


 * Dalaran Crater
 * An enormous crater where Dalaran once stood, encased with a violet-colored magical shield orb.


 * Shaper's Terrace
 * A new titan-related area in Un'Goro Crater, accessible by waygate from Sholazar Basin.


 * Old Stratholme
 * A level 80 wing of the Caverns of Time that takes players back to Arthas's Culling of Stratholme in Warcraft III.

Factions and organizations
Various organizations, factions and new races are highlighted in the expansion. Note that no new playable races have so far been implemented.

Reputation grinding
A new faction tabard system was implemented called "Championing" where wearing a tabard of a certain faction gives you rep with that faction for kills in level 80 instances in lieu of existing faction rep (which would only be the Alliance Vanguard or Horde Expedition meta-factions). This is to combat the feeling that gaining rep with factions is a long grind and that there is no flexibility for players to choose which factions they gain rep with.

Nexus War
When Malygos regained his senses, he quickly realized what had happened during his absence. The mortal races had manipulated magic and used it for their own personal gain. As a result, the Burning Legion had nearly been summoned again by the reckless Kael'thas Sunstrider and his felblood elves. Confident that there is no other solution, Malygos has declared war on every spell-caster and wishes to annihilate their kind and drain all of Azeroth's magic. However, there are groups that oppose him and fight for their own survival or for that of others.


 * Kirin Tor
 * The Kirin Tor - a group of powerful wizards - have moved their capital Dalaran to Northrend to fight off the blue dragonflight, along with the Undead Scourge. Being fanatic magic-users, they are directly influenced by the war Malygos has begun. Not only does he slowly drain all Azeroth's magic, but he also intends to slay all casters. The Kirin Tor oppose him directly in his assault and fight for the fate of their world.


 * Blue Dragonflight
 * The Aspect of Magic and the leader of the blue dragonflight - Malygos - has started a war with the mortal races for their reckless use of magic. Using his flight, Malygos now seeks to divert Azeroth's ley lines to his own home, the Nexus, by the use of giant constructs known as Surge needles, and send the energies out in the Twisting Nether, so no one will be able to use it anymore. He has not only ordered his fellow Blue dragons to slay the mortal spellcasters but also to take down all that would help these "criminals".


 * Wyrmrest Accord
 * As the overseers of Life on Azeroth, the red dragonflight closely watches all wars and observes all conflicts. While they usually do not interfere they now deem it necessary to enter the front lines themselves. Malygos's plan, to remove all magic from Azeroth, would have disastrous consequences for the entire world. Such catastrophes would cost countless lives, much more than all those that have fallen during the Nexus War. Thus Alexstrasza - the leader of the Red Dragonflight - has called upon the Wyrmrest Accord, a union between all Dragonflights to find a way to end Malygos's insanity and stop his reckless crusade.

Horde Expedition
Horde Expedition is the combined force of the Horde in Northrend, spearheaded by the Warsong Offensive.


 * Warsong Offensive
 * Garrosh Hellscream commands the Horde's main expeditionary forces as they make their way into Northrend to face Arthas and the armies of the Scourge.


 * The Hand of Vengeance
 * The Forsaken tasked by Sylvanas Windrunner with enacting Undercity's vengeance against Arthas by delivering the latest strain of their deadly Plague of Undeath.


 * The Taunka
 * These hardy people are cousins of the tauren and have become valuable scouts for the armies of the Horde as they march northward.


 * The Sunreavers
 * Traditionally barred from Dalaran, the Horde has been accepted into the city through the efforts of Archmage Aethas Sunreaver. His blood elf followers have taken up his name and watch over the ward known as Sunreaver's Sanctuary.

Alliance Vanguard
Provoked by the attack on Stormwind, the Alliance has gathered its forces to march upon Icecrown Citadel and put an end to the Lich King's reign.


 * Valiance Expedition
 * The main armies of the Alliance have arrived upon the shores of Borean Tundra, where they reinforced Valiance Keep with their sheer numbers.


 * Explorers' League
 * Eager to find out more about their past, the Explorers' League was quick to travel to Northrend. They're especially interested in the titan city of Ulduar which is said to hold much information about the ancestors of the dwarves, gnomes, and humans alike. In addition, they've opened up several dig-sites in an attempt to reveal what's hidden in the earth.


 * Frostborn
 * The Frostborn are a faction of a newly discovered dwarf, the frost dwarves. This mysterious race of dwarves makes its home in the Storm Peaks. They've recently befriended members of the Explorers' League and welcome Alliance members within their settlements. Their leader Yorg Stormheart seems to suffer from a strange amnesia; it is rumored that he used to be an important member within the Alliance.


 * Silver Covenant
 * Disgusted and outraged by the founding of the blood elven race, the remaining high elves have united under the banner of Vereesa Windrunner as the Silver Covenant. The Covenant consists primarily of a militant core that has joined forces with the Alliance in Northrend.

Undead Scourge

 * Dragonflayer Clan
 * The Dragonflayer Clan is one clan of vrykul, a race of half-giant warriors native to the Howling Fjord. They have recently allied themselves with the Scourge and wish to join its ranks. These formidable warriors have begun attacking Horde and Alliance settlements, and many of the vrykul are pouring out of the fortress of Utgarde Keep.

Opposition of the Scourge

 * Argent Crusade
 * The Knights of the Silver Hand and the soldiers of the Argent Dawn have merged into this new organization, headed by the re-inspired Highlord Tirion Fordring. They seem to be capable of something neither the Alliance nor the Horde could fulfill; they're fighting at the front lines of Icecrown.


 * Knights of the Ebon Blade
 * A counter to the Knights of the Silver Hand, the Knights of the Ebon Blade are an order of renegade death knights who have broken away from the Scourge. They are led by Highlord Darion Mograine, the son of Alexandros Mograine.


 * The Nerubians
 * A race of spider-humanoids that once controlled all of Northrend before the coming of the Lich King. Now, they live mainly in the lower reaches of their destroyed kingdom Azjol-Nerub and other scattered conclaves. It is speculated that they serve the Old God, Yogg-Saron, within their city. However, conversations with Kilix the Unraveler and Archmage Lan'dalock seem to imply they are at odds with him and his servants, the Faceless Ones.

Natural inhabitants

 * Kalu'ak
 * The Kalu'ak are tuskarr, a humanoid walrus people that lives in Northrend. Although seen throughout Northrend, they make their homes primarily in the Borean Tundra. Their capital city is Kaskala and it is a fishing area. They also have Kamagua, a settlement in the Howling Fjord. Moa'ki Harbor is situated in the Dragonblight.


 * Sons of Hodir
 * The Sons of Hodir are a faction of frost giants located in Storm Peaks. They are a war-like race that makes its home in Dun Niffelem.

Dungeons and End-game Content


The expansion added group content in a similar fashion to The Burning Crusade, and the "heroic dungeon" format was preserved. Many new 5-man, 10-man, and 25-man dungeons are located in Northrend. The expansion has as many 5-man instances as the previous expansion and all 25-man raids can also be completed as a 10-man group due to the popularity of Karazhan. Despite speculation, solo dungeons have not been implemented. There are no lengthy attunements for any dungeon.

There were three raid dungeons and twelve 5-man dungeons (eight for leveling up and four max-level, each with heroic versions) at release. Heroic access also no longer requires any faction reputation and are available simply by reaching level 80. All 5-man dungeons were said to have been designed to last around an hour, but this seems to be incorrect as some instances (especially The Violet Hold) can easily be completed in nearly half the time.

Battlegrounds
Strand of the Ancients is a new siege warfare-style battleground south of Dragonblight featuring siege weapons. 15 people are on each team, and games can last a maximum of 20 minutes if neither side captures the Titan Relic. Players can mount up in Siege Engines, a four-passenger vehicle with spots for the driver, gunner and two passengers with all passengers protected from incoming fire. Players on foot can also take part in the siege by using Seaforium Charges to attack the walls and turrets to defend the walls.

Isle of Conquest, a battleground introduced in patch 3.2.0, Call of the Crusade, pitches teams of up to 40 players against each other in a massive battle over this small island off Northrend's northern coast. To win, your team will need to make use of the island's unique strategic locations including an oil derrick, a siege workshop, and a fully equipped airship hangar. You will deploy devastating siege weaponry on the field; Light have mercy on anyone caught between you and your ultimate target, the general holed up in the enemy keep.

Arenas
Two new Arenas are also introduced in the expansion. One in the Orgrimmar Arena and the other in a new Dalaran Arena in Dalaran's sewers. These arenas introduce moving objects such as pillars and waterfalls, and damaging objects such as spikes in arenas and other such mechanics to create dynamics with line of sight and gameplay.

World PvP
PvP mechanics are extended in WotLK, with the addition of a dedicated PvP zone (even on PvE servers) in central Northrend called Wintergrasp. There is no requirement to visit the zone, but the benefit is that all bosses in instances drop a token, similar to Spirit Shards in Auchindoun, when your faction holds the keep everyone is fighting for. Players are able to use these tokens to purchase gear.

Siege weapons are the predominant method of attack and defense as there are no Seaforium Charges to be found. Players start off with the Catapult, an anti-personnel weapon that does minimal siege damage to buildings. Upgrades include the Demolisher, a vehicle with a ram attack and turret controlled by a single player, and the siege engines from Strand of the Ancients.

Previews of the zone also included aerial vehicles, the flying machine and gnomish bomber, as well as the anti-aircraft goblin Shredder, but these have yet to be implemented due to balance issues. Wintergrasp itself is a no-fly zone and will dismount aerial players wishing to fly through it.

Additionally, control of Wintergrasp confers access to the Vault of Archavon, a quick onyxia-style encounter capable of dropping Tier 7 loot or equivalent PvP gear. An additional boss was added in Patch 3.1.0 who drops Tier 8 or equivalent loot. Koralon the Flame Watcher being added in Patch 3.2.0 with Tier 9, and Toravon the Ice Watcher in Patch 3.3.0 with Tier 10.

Hero classes
The expansion introduced the long-awaited concept of Hero classes to World of Warcraft. Hero classes will generally consist of classes from Warcraft III that were too strong or did not make sense as a level 1. Wrath of the Lich King's Hero class is the death knight.

Death knight


World of Warcraft's first hero class, the death knight is accessible to players after having a character reach level 55. Once unlocked, the death knight, starting at level 55, will then complete a series of quests in Acherus: The Ebon Hold and the Scarlet Enclave that will explain their defection and background. Originally, death knights were only allowed to be created on a realm with a preexsisting level 55 character for that account, but now, as long as there is a level 55 present on the account, a death knight can be constructed on any realm. A single death knight is allowed per realm.

The death knight is a plate-wearing DPS/tank class (albeit one that is unable to use a shield) that uses a brand new resource system based primarily on cooldowns. Rather than the existing mana/rage/energy mechanics, the death knight uses six runes, two runes each of three types, frost, blood, and unholy, which are refreshed on a ten second timer. Death knights also have access to runic power, which is generated much in the same way as rage.

Professions and skills
Professions can be leveled to 450 skill points from the Burning Crusade's 375 skill cap, while leveling professions from 300-375 has been made easier.

Continuing in the tradition of The Burning Crusade of introducing a new profession with an expansion, Wrath of the Lich King's new profession is inscription.

Inscription
The inscriber creates scrolls, vellum, glyphs and other paper paraphernalia. Scrolls are direct analogues of the various scrolls dropped from mobs (like ). Vellum are used as a target for an enchanter's spells (/) such that the vellum themselves (now also called scrolls) can be used to enchant items and are sold on the Auction House.

Glyphs come in two varieties, major and minor. Major glyphs are used to augment a player's combat spells and abilities, such as increasing the damage multiplier on Ice Lance or clearing polymorphed targets of damage over time effects. Minor glyphs are used for cosmetic effect, to reduce the mana cost of buffs or remove reagent requirements.

Bestiary

 * Nerubian vizier
 * Plague Eruptor
 * Shovel tusk
 * Iron Dwarf
 * Taunka
 * Magnataur
 * Jormungar
 * Flesh giant
 * Darkfallen
 * Ice Troll
 * Proto-dragon
 * Wendigo

Levels, spells, and talents
The expansion allows characters to level to 80, adding 10 additional talent points to their disposal and extending the talent trees further to allow for 51-point talents. Leveling from 70 to 80 takes approximately the same amount of time as leveling 60 to 70. You can now switch between two pre-set talent specializations freely after visiting your class trainer and paying a one-time fee of 1000g for Dual Talent Specialization. Respeccing within either of those specs will still cost the normal respec fee.

Extended character customization
Players are also able to change hairstyles of existing characters using barber shops. However, players are not allowed to change their characters' body shape or size. As of December 10, 2008, you are able to re-customize your characters' facial attributes and gender for $15 here.

Voice emotes
Death knight voices are modulated for each race so that they sound deeper and have an echo.

Items

 * Blizzard has introduced Heirloom Items (sometimes referred to as Legacy Items) with the expansion. Essentially, these items are bound to the player's account, with the ability to ship the items between characters on the realm the item was discovered.
 * The color for heirloom items is gold, very similar as seen to the one in Diablo II: Legacy . Heirloom items are still not the same as artifact items, even if they (for now) use the same coloring for names.


 * PvP armor is different from the PvE armor entirely in looks and colors.


 * 25-man raids drop more loot than 10-man versions and are separated with a full tier of item stats.


 * The token system remains for PvE. Stone Keeper's Shards are be awarded from all instances to players in the faction that controls Wintergrasp. They are used to purchase heirlooms, Jewelcrafting designs, gems, shoulder enchants and mounts.


 * Blizzard made a design shift to reduce the number of items they must design and to prevent unwanted drops being wasted. The end result was that more classes use the same items. This was accomplished by reducing the amount of varied stats different classes and specs need so that 3 classes can share the same items.


 * Players are able to “learn” a mount or non-combat pet much like learning a spell, recipe, or new ability, and these creatures then show up on a new Pet tab within the Character Info section of the interface. Players are able to access and preview their learned mounts and vanity pets through this tab. Once learned, the pet icon or mount icon no longer appears in bag spaces or bank spaces. This inventory space is made available once again for other adventuring needs. Pets can still be set to hotkeys by dragging them to the hotkey bar, much like any other spell or ability.

Mounts
In the expansion, mounts no longer take up space in your bag; they can be retrieved from the pet tab. Lost mounts and pets can be restored from a stable master.

Here is a listing of the new mounts:
 * and are available to purchase when you have Revered and Exalted reputation with the Sons of Hodir faction.
 * woolly mammoth mount can be purchased in Wintergrasp for 300 s.
 * Reins of the Traveler's Tundra Mammoth and vanity mount for sale from the exotic pet vendor Mei Francis in Dalaran for  and  respectively, although the price is reduced with reputation. Note that the caravan mammoth reads "This is a very fast three person mount that carries vendors."
 * and Tailoring mounts can be crafted with 380 and 420 tailoring respectively.
 * Acherus Deathcharger, the Deathknight class mount.

Technical information
The expansion enhanced the World of Warcraft's graphical engine; for example, a new shading system was used in ice caves, while flame animations are noticeably more detailed. In addition, the art for the expansion looked more like "classic Warcraft" (gothic fantasy), and less like Outland art (high fantasy).

Please note that to install the World of Warcraft: Wrath of the Lich King expansion, you must have the original World of Warcraft and the World of Warcraft: The Burning Crusade expansion.

Spectators
The ability to spectate arenas is still on the Blizzard to-do list, but they are being careful about it. Blizzard would also like to add this ability to raids too. In both cases it would be an opt-in feature only.

These are directly from the site.

Paradigm Shift: Dungeons and Raids
Heroic dungeons were one of the most popular innovations of the previous expansion, so it’s no surprise Heroic mode will return in Wrath of the Lich King. Just as in The Burning Crusade, every five-person dungeon will have a Heroic variant that will present players with an added challenge and improved rewards.

One exciting new feature in Wrath of the Lich King is that all raid content will be available as either a 10- or 25-person dungeon with completely independent progression paths. Both the 10- and 25-person versions will be the same dungeon; the look, layout, and design of the dungeon will remain the same. However, each will be adjusted, tuned, and balanced for its respective player size.

In Wrath of the Lich King, players can expect both 10- and 25-person raid progression paths to get increasingly difficult as they adventure to their final battle with Arthas. This new gameplay mechanic will allow more players to enjoy the raid content of Wrath of the Lich King in their preferred play style. Because it takes more effort to get 25 people together than it does for 10, players who participate in the 25-person raid progression path will receive higher quality and more loot than those who play the 10-person versions.

In addition, players will never be required to attune in a 10-person raid to progress to a 25-person raid in the progression path. Raid lockouts are same-size as well, so joining a 25-person raid for a dungeon will not lock a player out from the 10-person version of the same dungeon. This freedom of choice between raid-progression paths will let personal preference play a much bigger role in how players experience the raid content of Wrath of the Lich King

NPCs can also ride upon the shoulders of larger NPCs, such as Excelsior on Hidalgo the Master Falconer, or Grand Necrolord Antiok on Thiassi the Lightning Bringer.

Achievements
The Achievement system is a system that will keep track of certain goals that characters have reached, such as complete zone exploration, pet and mount collecting, and PvP kills.
