22 ACTION_T_SET_PHASE Phase Sets the current phase to (param1)
23 ACTION_T_INC_PHASE Value Increments the phase by (param1). May be negative to decrement phase but should not be 0.
24 ACTION_T_EVADE No Params Forces the creature to evade. Wiping all threat and dropping combat.
25 ACTION_T_FLEE No Params Causes the .creature to flee. Please use this action instead of directly casting this spell so we may change this when a more correct approach is found.
25 ACTION_T_FLEE_FOR_ASSIST No Params Causes the creature to flee for assistence (at low helth mostly).
26 ACTION_T_QUEST_EVENT_ALL QuestId Calls GroupEventHappens with (param1). Only used if it's _expected_ event should complete for all players in current party
27 ACTION_T_CASTCREATUREGO_ALL QuestId, SpellId Calls CastedCreatureOrGo for all players on the threat list with QuestID(Param1) and SpellId(Param2)
