Fires for Combat Log events such as a player casting a spell or an NPC taking damage.

  • COMBAT_LOG_EVENT only reflects the filtered events in the combat log window
  • COMBAT_LOG_EVENT_UNFILTERED (CLEU) is unfiltered, making it preferred for use by addons.

Both events have identical parameters. The event payload is returned from CombatLogGetCurrentEventInfo(), or from CombatLogGetCurrentEntry() if selected using CombatLogSetCurrentEntry().

Power Type[]

{{#if: [[Enum.PowerType}}
Value Field Description
-2 HealthCost
-1 None
0 Mana Mana will range from 0 to the maximum mana a unit has. Player mana pools are of a fixed size for all specializations except Arcane Mages, whose mastery increases their maximum mana. Players naturally regenerate mana at a constant rate dependent on their specialization, both in and out of combat, and some abilities and effects (ex Spell shadow burningspirit [Life Tap], Ability priest flashoflight [Power Word: Solace], Ability shaman watershield [Resurgence]) can directly generate mana. This is the default power type for most non-player units, although there are exceptions.
1 Rage Rage is used by Warriors and Druids in bear form. Rage ranges from 0 to 100, but may be increased via player talents. Rage is generated by abilities and, for some specializations, taking damage or dealing damage with auto-attacks. Rage will decay to 0 while out of combat.
2 Focus Wrath-Logo-Small Focus is used by Hunters and their pets. Focus ranges from 0 to 100, though this can be increased by spec passives. It has a relatively slow passive regeneration rate, but certain abilities will generate focus directly.
3 Energy Energy is used by Rogues, Monks, and Druids in cat form. Energy ranges from 0 to 100, but may be increased via player talents and spec passives. Energy regenerates rapidly.
4 ComboPoints Warlords of Draenor Combo Points are used by Rogues and Druids in cat form. Combo Points range from 0 to 5, but can be increased up to 6 by the [[Deeper Stratagem] Rogue talent or to 10 by the Ability rogue slaughterfromtheshadows [Anticipation] Rogue talent. Combo Points are generated by abilities, talents, and passives, and are consumed by Finishing Moves to increase their potency. Combo Points will decay to 0 while out of combat. This value was previously used for hunter pets' happiness, which was deprecated in Cataclysm.
5 Runes Wrath-Logo-Small Runes are used as a power type for Death Knights. Deathknights have 6 runes available. As of Legion, Deathknights no longer have different types of runes, and instead all 6 runes can be used for any ability which consumes them. Up to 3 runes can be regenerating at a time, with the other 3, if depleted, effectively having a recharge time of up to twice the normal rune recharge time. Rune recharge rate can be accelerated through Spell shadow rune [Runic Corruption], or runes can be instantly activated by Spell deathknight bloodtap [Blood Tap] or Inv misc rune 10 [Runic Empowerment], as well as a number of talents and set bonuses.
6 RunicPower Wrath-Logo-Small Runic Power is used by Death Knights. Runic Power ranges from 0 to 100, though it can be increased by talents and set bonuses. It is gained by spending runes on abilities, or directly by certain abilities, talents, and passive effects. Runic Power is spent on a limited set of damaging abilities, many of which help regenerate additional runes. Runic Power will decay to 0 while out of combat.
7 SoulShards Wrath-Logo-Small Inv misc gem amethyst 02 [Soul Shards] are collected by Warlocks, and range from 0 to 5, represented the number of filled Soul Shards. As of Legion, this resources is now used by all 3 Warlock specializations. Soul Shards will naturally regenerate or decay as needed while out of combat until they reach 3 out of 5 filled. As of Patch 7.2.5, if the "unmodified" boolean argument to UnitPower is provided, the values returned for Soul Shards will range instead from 0 to 50, with each 10 representing a filled Soul Shard. This is to account for the ability of Warlock_talents#Destruction warlocks to generate fractional Soul Shards in increments of 1/10th, similar to how Burning Embers functioned in prior expansions.
8 LunarPower Legion Astral Power is used by Druids in moonkin form. Astral power goes from 0 to 100. Astral power will decay to 0 while out of combat.
9 HolyPower Wrath-Logo-Small Holy Power is used by Retribution Paladins. Holy Power ranges from 0 to 5, and will decay to 0 while out of combat.
10 Alternate Cataclysm New power type since Cataclysm. Known uses: sound level on Atramedes, corruption level on Cho'gall, consumption level while in Iso'rath.
11 Maelstrom Legion The new Shaman resource in Legion, used by both Enhancement and Elemental shamans. Maelstrom ranges from 0 to 100 for Elemental and 0 to 150 for Enhancement, though it can be increased by talents and artifact traits. Maelstrom will decay to 0 while out of combat.
12 Chi Mists of Pandaria Chi is used by Windwalker Monks. Chi ranges from 0 to 5, and will decay to 0 while out of combat.
13 Insanity Legion Insanity is used by Shadow Priests. Insanity is generated by most Shadow Priest abilities, and will be consumed at an ever-increasing rate while the priest is in Spell priest voidform [Voidform], until it reaches 0 and the priest leaves Voidform (or dies horribly if Achievement boss generalvezax 01 [Surrender to Madness] is active). Insanity will decay to 0 while out of combat even if the priests is not in Spell priest voidform [Voidform].
14 Obsolete Mists of Pandaria Burning Embers were used by Destruction Warlocks prior to Legion, which consolidated all warlock specs to use Inv misc gem amethyst 02 [Soul Shards]. Value returned would range from 1 to 3 (4 with Inv glyph majorwarlock [Glyph of Burning Embers], representing number of completely filled Burning Embers. If a third argument "true" is included with UnitPower or UnitPowerMax, the value would instead range from 0 to 30 (40 with Inv glyph majorwarlock [Glyph of Burning Embers]), representing the individual segments in each Ember. Each Ember had 10 segments, and most effects that generate Embers generate 1 segment per effect (for example, a cast of Incinerate generates one segment, so 10 casts generates a full Ember). As of Legion, this power type is now obsolete.
15 Obsolete2 Mists of Pandaria Ability warlock eradication [Demonic Fury] was used by Demonology Warlocks prior to Legion, which consolidated all warlock specs to use Inv misc gem amethyst 02 [Soul Shards]. Value returned would range from 0 to 1000. As of Legion, this power type is now obsolete.
16 ArcaneCharges Legion Arcane Mage resource. Arcane Charges range from 0 to 5. They are generated by casting Spell arcane blast [Arcane Blast] and Spell nature wispsplode [Arcane Explosion], and consumed by Ability mage arcanebarrage [Arcane Barrage], though a number of abilities benefit from having charges without consuming them. Arcane Charges will decay to 0 while out of combat.
17 Fury Legion Havoc Demon Hunter. Fury is generated by Inv weapon glave 01 [Demon's Bite], as well as a number of talents, and consumed by most Havoc abilities. Fury ranges from 0 to 100, though artifact traits can increase this to up to 170. Fury will decay to 0 while out of combat.
18 Pain Legion Vengeance Demon Hunter. Pain is generated by several Vengeance abilities (ex. Ability demonhunter hatefulstrike [Shear], Ability demonhunter felblade [Felblade]), and consumed by several others (ex. Ability demonhunter soulcleave [Soul Cleave], Ability demonhunter demonspikes [Demon Spikes]), predominantly for defensive purposes. A small amount of Pain is also generated when the Demon Hunter takes damage. Pain ranges from 0 to 100, and will decay to 0 while out of combat.

Advanced Combat Log[]

Combat log messages may be written to the World of Warcraft\_retail_\Logs\WoWCombatLog.txt file for external parsing purposes. This feature can be enabled with LoggingCombat(true) or toggled with the /combatlog slash command. Combat logging was added on patch 1.7.0[2]


This log line is added when combat logging starts.


Advanced parameters[]

There can be up to 39 parameters, in order:

  • 9 base params (subevent, source and dest unit)
  • 0 to 3 prefix params (spell/environmental)
  • 17 advanced params
  • 0 to 10 suffix params

Advanced parameters require CVar advancedCombatLoggingDefault: 0
Whether we want advanced combat log data sent from the server
(added in 5.4.2)[3] to be enabled for meaningful values.

Multiple Values[]

Some events can have multiple values for a param, delimited by a | vertical bar, for example 3|4,120|5,120|5,25|5 for powerType, currentPower, maxPower, powerCost respectively. This is the case when spells use more than one powertype to cast.

This logging feature was added on patch 7.0.3

New Logging Feature: COMBATANT_INFO | 2016-01-13 00:00 | Blizzard Entertainment Celestalon

Whenever an ENCOUNTER_START event occurs, a new “COMBATANT_INFO” log line will also be printed for each player in the instance. The current data structure for COMBATANT_INFO is as follows, but is subject to change based on feedback and technical needs:

COMBATANT_INFO,playerGUID,Strength,Agility,Stamina,Intelligence,Dodge,Parry,Block,CritMelee,CritRanged,CritSpell,Speed,Lifesteal,HasteMelee,HasteRanged,HasteSpell,Avoidance,Mastery,VersatilityDamageDone,VersatilityHealingDone,VersatilityDamageTaken,Armor,CurrentSpecID,(Class Talent 1, ...),(PvP Talent 1, ...),[Artifact Trait ID 1, Trait Effective Level 1, ...],[(Equipped Item ID 1,Equipped Item iLvL 1,(Permanent Enchant ID, Temp Enchant ID, On Use Spell Enchant ID),(Bonus List ID 1, ...),(Gem ID 1, Gem iLvL 1, ...)) ...],[Interesting Aura Caster GUID 1, Interesting Aura Spell ID 1, ...]

Some clarifications about a few of those elements:

  • Stats – Those are the current stat values at the time of the log line. Secondary stats are in terms of the Rating amount, not a %.
  • Armor – This is the Armor amount before multipliers (such as Bear Form).
  • Talents – A list of the selected talents. Today’s build will print this ID as a TalentID, a record type that is not dataminable. This will be fixed in a future build to be the SpellID of the talent.
  • Artifact Traits – This will be a list of the selected traits for the character’s current specialization’s artifact (even if it’s not equipped). The Artifact Trait ID is an ID to a new record type to 7.0, which should be dataminable already. Trait Effective Level is the number of points placed in that talent. Note that some Relics will allow this to go beyond the max.
  • Equipment – This is a list of all equipped gear on the character. The first ID is the standard Item ID of the item, followed by its ilvl. After that is a list of enchants on the item, one of each of the 3 possible enchantment types (using the ItemEnchantment ID).
  • Interesting Auras – This is a list of interesting auras (buffs/debuffs) that we have manually flagged to be included in this log line. We’ll welcome feedback about what should be included here but currently plan for set bonuses, well fed, flasks, combat potions, Vantus runes, and player buffs. Nothing has been flagged for this yet, so you won’t see anything here in the current build.

Event Descriptions[]


Event Prefix Description
SPELL_ Spell is the prefix for most effects even if the spell is a DoT or channeled. IE when the spell begins to be cast, SPELL_CAST_START is fired and not SPELL_PERIODIC_CAST_START. This is the same with _MISS, _FAILED, etc.
SPELL_PERIODIC Only the effects that are periodic start with this PREFIX. IE: Successfully casting a DoT only happens once therefore even though the spell is periodic use the SPELL_ prefix. However, the damage is periodic so it will start with SPELL_PERIODIC_. 90% of the time you will only care about _DAMAGE or _HEAL.
SPELL_BUILDING Wrath-Logo-Small damage or healing that can affect destructable buildings.


Event Suffix Description
_DAMAGE Triggered on damage to health. Nothing Special. (overkill returns a number greater than or equal to zero)
_MISSED Triggered When Effect isn't applied but mana/energy is used IE: ABSORB BLOCK DEFLECT DODGE EVADE IMMUNE MISS PARRY REFLECT RESIST
_HEAL Triggered when a unit is healed
_HEAL_ABSORBED Triggered when a spell absorbs the healing done by another spell. Extra info is provided for the healer and the heal spell, as well as the amount absorbed.
_ENERGIZE Any effect that restores power. Spell/trinket/item set bonuses can trigger this event. IE: Vampiric Touch, or Mark of Defiance (Trinket)
_DRAIN Same as _ENERGIZE but this time you are losing power. Caused by enemies.
_LEECH Same as _DRAIN, but the source unit will simultaneously receive the same kind of power (specified in extraAmount)
_INTERRUPT Spellcasting being interrupted by an ability such as Kick or Pummel.
_DISPEL A buff or debuff being actively dispelled by a spell like Remove Curse or Dispel Magic. The source is the caster of the aura that was dispelled, and the destination is the target which was dispelled (needs verifying).
_DISPEL_FAILED A failed attempt to dispel a buff or debuff, most likely due to immunity.
_STOLEN A buff being transferred from the destination unit to the source unit (i.e. mages' Spellsteal).
_EXTRA_ATTACKS Unit gains extra melee attacks due to an ability (like Sword Sepcialization or Windfury). These attacks usually happen in brief succession 100-200ms following this event.
_AURA_APPLIED Triggered When Buffs/Debuffs are Applied. Note: This event doesn't fire if a debuff is applied twice without being removed. IE: casting Vampiric Embrace twice in a row only triggers this event once. This can make it difficult to track whether a debuff was successfully reapplied to the target. However, for instant cast spells, SPELL_CAST_SUCCESS can be used.
_AURA_REMOVED Triggered When Buffs/Debuffs expire. The souce is the caster of the aura which faded, and the destination is the target from which the aura faded (needs verifying).
_AURA_APPLIED_DOSE Triggered by stacking Debuffs if the debuff is already applied to a target. IE: If you cast Mind Flay twice it causes 2 doses of shadow vunerability, the first time it will trigger, SPELL_AURA_APPLIED (arg10 = shadow vulnerability), and SPELL_AURA_APPLIED_DOSE (arg10 = shadow vunerability) the second. The last argument reflects the new number of doses on the unit.
_AURA_REMOVED_DOSE The opposite of _AURA_APPLIED_DOSE, reducing the amount of doses on a buff/debuff on the unit.
_AURA_REFRESH Resets the expiration timer of a buff/debuff on the unit.
_AURA_BROKEN A buff or debuff is being removed by melee damage. The source is the name of the caster of the aura that was broken, and the destination is the target which the aura broke off of (needs verifying).
_AURA_BROKEN_SPELL A buff or debuff is being removed by spell damage (specified in extraSpell...). Source and destination is the same as the above.
_CAST_START Triggered when a spell begins casting. Instant spells don't invoke this event. They trigger _CAST_SUCCESS, _FAILED instead.
_CAST_SUCCESS Triggered when an instant spell is cast or when a spellcast finishes and doesn't fail. This isn't triggered when the spell misses. On a miss SPELL_MISS will be triggered instead.
_CAST_FAILED If the cast fails before it starts (IE invalid target), then _CAST_START never triggers. However it is possible for a cast to fail after beginning. (IE you jump, move, hit escape etc.)
_INSTAKILL Immediately kills the destination unit (usually happens when warlocks sacrifice their minions).
_CREATE Creates an object (as opposed to an NPC who are 'summoned') like a hunter's trap or a mage's portal.
_SUMMON Summmons an NPC such as a pet or totem.
_DISSIPATES Fires when Gas Clouds are being extracted with Zapthrottle Mote Extractor
