Emeriss (Classic)

Emeriss was one of the four Dragons of Nightmare. Since WoW's 13th Anniversary, Emeriss is available during the anniversary event.

Overview
Emeriss was one of the Emerald Dragons. The other Emerald Dragons are Lethon, Ysondre, and Taerar. These dragons are world spawns located in Duskwood (Twilight Grove), the Hinterlands (Seradane), Feralas (Dream Bough), and Ashenvale (Bough Shadow). They were raid level difficulty. However, some dragons are more challenging than others. Emeriss was considered to be the second hardest. However, this was debatable as the difficulty of Lethon largely depended on the quality and experience of one raid member. Emeriss, by comparison, required the attention and focus of all your raid members. The dragon was very easy if everyone did their job well but she would make quick work of your raid if mistakes happened.

All four dragons shared the Sleep (summoning "Dream Fog"), Noxious Breath, Tail Sweep, Mark of Nature and Aura of Nature abilities. Each dragon also had a few unique abilities. One of these was considered the dragon's ace move, and would be performed when the dragon lost 25 ± 5% of its max life. In other words, the ace move would only be performed three times; when the dragon was at 25%, 50%, and 75% life. When it was performed, the dragon would also yell something.

Used by all the Dragons of Nightmare

 * Spell nature abolishmagic.png Seeping Fog - Summons two clouds of Dream Fog that will chase random players around the dragon and put them to sleep for 4 seconds.
 * spell shadow lifedrain02.png Noxious Breath - Deals 3000 Nature damage and applies a 30 second DoT that increases cooldowns on all abilities by 10 seconds and inflicting 350 to 450 Nature damage every 3 seconds. The DoT can stack up to 6 times. The main tank should be the only one affected by this.
 * inv misc monsterscales 05.png Tail Sweep - Inflicts 925 to 1075 damage on enemies in a 30 yards cone behind the dragon, knocking them back.
 * spell magic featherfall.png Summon Player - Teleports the player who has the most aggro in front of the dragon if the player tries to run out of combat. This ability has first been noted after patch 2.0.1.
 * spell nature spiritarmor.png Mark of Nature - If players are killed by a nightmare dragon, they will be afflicted by a 15 minute debuff called Mark of Nature. If engaging the dragon during this time, they will be slept for 2 minutes rather than 4 seconds as with the Dream Fog.
 * spell nature spiritarmor.png Aura of Nature - A invisible pulsing aura that interrupts actions like eating, drinking and bandaging when close to the dragon. Will trigger the 2 minute sleep when combined with Mark of Nature.
 * All the Dragons of Nightmare are also immune to nature damage.

Abilities exclusive to Emeriss

 * spell holy harmundeadaura.png Volatile Infection - A dispellable disease that affects a random target within 100 yards for 2 minutes. This deals 875 to 1125 Nature damage to the player and all players surrounding him/her every 5 seconds.
 * ability creature cursed 03.png 25% ability: Corruption of the Earth - Affects all players in range. 10 second Shadow DoT that deals 20% of the player's max health every 2 seconds. It cannot be dispelled and has a 100 yard range.
 * inv mushroom 02.png Putrid Mushroom - When a player dies, a Putrid Mushroom spawns at their corpse. This deals 600 Nature damage per second to any surrounding player.

Strategy

 * Pull Emeriss to the raid, then turn her around so she is facing up the ramp. Healing should be on the MT, and everyone should be away from the tail. Ranged should be at a good distance and not clustered so they can avoid the sleep clouds more easily.
 * Have the second tank run in to cover for the MT should he be put to sleep. Neither of them will be able to taunt.
 * After a while, call for the raid to assist. Melee should hit her hind legs (rather than her butt) to avoid getting tailwhipped. Ranged should be spread out at max range.
 * Steady dps, have the majority of the healers on the MT; make sure the secondary tank knows what to do if he takes aggro cause the MT got sleeped.
 * At 75%, 50%, 25% health, have melee move further than 100 yards out of range to avoid her AoE DOT. (Have priests move as well, and druids / pallies/ shaman healing MT during this DoT).
 * Be sure you don't get slept during her Corrupted Earth DoT, watch your positioning! Consider putting a healing group on her left, and another on her right, in case this happens.
 * When Emeriss performs Corruption of the Earth, she will yell "Taste your world's corruption!". This is the cue for the group to melee and the rest of the group to return to their original positions.
 * Do not die! Use a potion or bandage where possible.
 * Greater Nature Protection Potions seemed to absorb damage from those who died and sprouted mushrooms.
 * Not a vital note for the fight, but the Noxious Breath DoT persists on the MT after Emeriss dies, for it's rather funny when the whole guild is celebrating when 5 seconds later the MT falls over dead. Just remember to heal him after Emeriss dies.

Trivia
When the dragons were released to the game, it was possible to counter Emeriss' Corruption of the Earth-spell with the device Ultra-Flash Shadow Reflector. This would cause the spell to be reflected, forcing Emeriss to kill herself within few seconds. The glitch was rapidly patched the week after when Blizzard had become aware of it.
