In Base Parameters, source GUID and destGUID, i've found 2 new Unit Type in addition to Player(0x0), NPC(0x3) and Pet(0x4):

If you perform a bit-wise AND on the GUID with the mask 0x00F0000000000000:

Result	Unit Type
0x0000000000000000	Player
0x0030000000000000	NPC
0x0040000000000000	Pet
0x0010000000000000	? Object ?
0x0050000000000000	? Controlled Object (aka turret, mount, ...) ?

Few exemples from my very limited french development CombatLog sample

Object(0x1)

fishing bob (Flotteur, dest of SPELL_CREATE)

wintergrasp central tower (Tour centrale de Joug-d'hiver, dest of SPELL_BUILDING_DAMAGE)

Controlled Object(0x5)

Wyrmrest Vanquisher (dest of SPELL_AURA_APPLIED/REMOVED BUFF)

Wyrmrest Defender (SPELL_AURA_A/R, SPELL_DAMAGE when your mount takes damage, UNIT_DIED)

I've found an odd quirk with the bit-masking technique, summoned pets, such as DK's gargoyles show up as NPCs, not pets. From a combat log:

5/14 19:55:57.030  SPELL_SUMMON,0x06000000027B533E,"Siyeg",0x514,0xF130006CB5004379,"Ebon Gargoyle",0xa28,49206,"Summon Gargoyle",0x20

Note that the destId is 0xF130006CB5004379 and when masked with 0x00F0000000000000 yields 0x0030000000000000 identifying it as an NPC not a pet as you might expect.

It doesn't look like _MISSED actually does NOT have an amount passed as its second suffix-specific parameter. Can anyone else verify either way? I only have access to limited logs right now. Farlox (talk) 10:31, 11 December 2008 (UTC)

According to Blizzard_CombatLog.lua, SWING_MISSED and SPELL_MISSED have up to two arguments: missType and amountMissed. A value for amountMissed is only possible when missType is RESIST, BLOCK, or ABSORB. Parser (talk) 21:20, 11 December 2008 (UTC)

There is also an event for arg2 called PARTY_KILL. This fires when a unit dies... I don't know more yet, I was killing random mobs. And there is SPELL_DISPEL when dispelling a debuff.

--Sharandris (talk) 21:42, 17 July 2008 (UTC)

The event PARTY_KILL occurs when you or a member of your group/raid kills something. Parser (talk) 00:14, 7 September 2008 (UTC)

I've added "pet happiness" to the power type. The only time I've encountered this value was for a SPELL_PERIODIC_ENERGIZE log event where someone's pet was energized by "Feed Pet Effect".

While investigating the possibilities of writing a parser for the text combat log, I've been investigating the blizzard interface data. Are there any serious reasons around here why I shouldn't put that info up here? PleegWat 20:36, 27 March 2008 (UTC)

What "info"? Posted by: EGingell (T|C|F) on 21:49, 12 June 2008 (UTC)

Event Descriptions Edit

Summary Of what I have learned about when events fire and when they don't: (Preliminary)

Prefixes Edit

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, ect.
SPELL_PERIODIC	Spell_PERIODIC Only the effects that are periodic start with this PREFIX. IE: Successfully casting a DoT only happens once therefor 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.

Suffexes Edit

Event Prefix	Description
_DAMAGE	Triggered on damage to health. Nothing Special
_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
_ENERGIZE	Any effect that restores energy/mana. 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 loosing energy/mana. Caused by enemies.
_LEECH
_INTERRUPT
_DISPEL_FAILED
_AURA_DISPELLED	AURA means buff/debuff. Any effect that can be seen in the combat frame is handled by aura events. This event is triggered when a buff/debuff is removed early.
_AURA_STOLEN
_EXTRA_ATTACKS
_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 dificult to track whether a debuff was sucessfully reapplied to the target. However, for instant cast spells, SPELL_CAST_SUCCESS can be used.
_AURA_REMOVED	Triggered When Buffs/Debuffs expire.
_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
_AURA_REMOVED_DOSE
_CAST_START	Triggered when a spell begins casting. Instant Cast and channeled spells don't invoke this event. They trigger _CAST_SUCCESS, _MISS instead.
_CAST_SUCCESS	Triggered when channeled spells begin or when instant cast spells are cast. This (obviously) isn't triggered when this spell misses. On a miss SPELL_MISS will be triggered instead. Also, spells that invoke _CAST_START don't trigger this event when they are done casting. Use _SPELL_MISS or _SPELL_DAMAGE or _SPELL_AURA_APPLIED to see when they were cast
_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
_DURABILITY_DAMAGE
_DURABILITY_DAMAGE_ALL
_CREATE
_SUMMON

School Strings Edit

In the current Blizzard_CombatLog.lua, Blizzard has a table with strings for combinations of schools. I'll paste it below. I'd like to know how to best describe this table in the article. Currently, these strings seem to only be used in the combat log name of a spell. As far as I can tell, they don't necessarily result in separate spell schools that need to be handled (though Frostfire is a completely new school). This seems to be the beginning of a much larger spell school table, but not yet?

Did Blizzard Take out this event??
