Buff related events

11/8/2008 This was removed with 3.02. Use UNIT_AURA instead.

Called when a buff or debuff is either applied to a unit or is removed from the player. (Further details to follow, study needed).

Also fired when you start eating and/or drinking (which really is only a buff being applied like any other).

Druid 

This event is also called when a Druid changes form (or prowl state). arg1 - arg9 are all nil in this case. These args are probably nil for other classes as well. Also, this event is called multiple times per form change.

Fired when a buff, debuff, status, or item bonus was gained by or faded from a player, pet, NPC, or mob.

arg1 

the UnitID of the entity

1-28-06: This event IS NOT fired when changing targets any longer.

Seems like the same as UNIT_AURA above (including arguments) but only for short buffs. As a Paladin, it was triggered each time I gained a 30 second buff (Paladin Seals), lost/canceled it, or switched targets from another player to myself. Needs more testing with other classes etc.

Fired when the current form changes.
