All params are signed 32-bit values (+/- 2147483647). Time values are always in milliseconds.
In case of a percentage value, use value/100 (ie. param = 500 then that means 500%, -50 = -50%)
[*] Phase mask is a bitmask of phases which shouldn't trigger this event. (ie. Phase mask of value 12 (binary 1100) results in triggering this event in phases 0, 1 and all others with exception for phases 2 and 3 (counting from 0).

-----------------------------
Parameter 1: Field_Number - The index of the Field Number to be changed. Use (http://wiki.udbforums.org/index.php/Character_data) for a list of indeces and what they control. Creatures only contain the OBJECT_FIELD_* and UNIT_FIELD_* fields. They do not contain the PLAYER_FIELD_* fields.

When activated, this action changes the target's flags by adding (turning on) more flags. For example, this action can make the creature unattackable/unselectable if the right flags are used.
Parameter 2: Target - The target type defining for whom the flags should be changed. The value in this field needs to be a valid Target Type as specified in the reference tables below.
When activated, this action changes the target's flags by removing (turning off) flags. For example, this action can make the creature normal after it was unattackable/unselectable if the right flags are used.
Parameter 1: AllowAutoAttack - If zero, then the creature will stop its melee attacks. If non-zero, then the creature will either continue its melee attacks (the action would then have no effect) or it will start its melee attacks on the target with the top threat if its melee attacks were previously stopped.
Parameter 1: If zero, then the creature will stop moving towards its victim (if its victim gets out of melee range) and will be stationary. If non-zero, then the creature will either continue to follow its victim (the action would have no effect) or it will start to follow the target with the top threat if its movement was disabled before.
Parameter 2: If non-zero, then stop melee combat state (if param1=0) or start melee combat state (if param1!=0) and creature in combat with selected target.
Parameter 1: The new phase to set the creature in. This number must be an integer between 0 and 31. Numbers outside of that range will result in an error.
When activated, the creature will immediately exit out of combat, clear its threat list, and move back to its spawn point. Basically, this action will reset the whole encounter.
Parameter 1: Target - The target type defining for whom the unit field should be changed. The value in this field needs to be a valid target type as specified in the reference tables below.

NOTE 2: PLEASE NOTE THAT EACH OF THE PARAM VALUES ARE ACTUAL PHASE NUMBERS NOT THE INVERSE PHASE MASK VALUE.
This is commonly used for Spellcasting NPC's who on Aggro may select at random a school of spells to use for the fight. Use this if you have up to 3 phases used, otherwise use Action 31 for more then 3 phases.
---------------------------------
31 = ACTION_T_RANDOM_PHASE_RANGE:
---------------------------------
Parameter 1: PhaseMin - The minimum of the phase range.
Randomly sets the phase between a range of phases controlled by the parameters. Sets the phase to a random id (Phase = PhaseMin + rnd % PhaseMin-PhaseMax).
NOTE 2: PLEASE NOTE THAT EACH OF THE PARAM VALUES ARE ACTUAL PHASE NUMBERS NOT THE INVERSE PHASE MASK VALUE.
This is commonly used for Spellcasting NPC's who on Aggro may select at random a school of spells to use for the fight. Use this if you have MORE then 3 phases used, otherwise use Action 30.
---------------------
32 = ACTION_T_SUMMON:
---------------------
Parameter 1: CreatureID - The creature template ID to be summoned. The value here needs to be a valid creature template ID.
Parameter 2: Target - The target type defining who the summoned creature will attack. The value in this field needs to be a valid target type as specified in the reference tables below. NOTE: Using target type 0 will cause the summoned creature to not attack anyone.
Parameter 3: SummonID - The summon ID from the creature_ai_summons table controlling the position (and spawntime) where the summoned mob should be spawned at.
NOTE: Param3 Value is the ID Value used for the entry used in creature_ai_summons for this action. You MUST have an creature_ai_summons entry to use this action.

-----------------------------
Parameter 1: CreatureID - The creature template ID. The value here must be a valid creature template ID.
Parameter 2: Target - The target type defining whom the quest kill count should be given to. The value in this field needs to be a valid target type as specified in the reference tables below.
When activated, this action will call KilledMonster() function for the player. It can be used to give creature credit for killing a creature. In general if the quest is set to be accompished on different creatures (e.g. "Credit" templates).
NOTE: It can be ANY creature including certain quest specific triggers
This is commonly used for giving the player Quest Credits for NPC kills (Many NPC's may use the same CreatureID for the Kill Credit)
----------------------------
34 = ACTION_T_SET_INST_DATA:
----------------------------
Parameter 1: Field - The field to change in the instance script. Again, this field needs to be a valid field that has been already defined in the instance's script.
Parameter 2: Data - The value to put at that field index.
Sets data for the instance. Note that this will only work when the creature is inside an instantiable zone that has a valid script (ScriptedInstance) assigned.
This is commonly used to link an EventAI script with a existing Script Library C++ Script. You make make things happen like opening doors on specific events that happen.
------------------------------
35 = ACTION_T_SET_INST_DATA64:
------------------------------
Parameter 1: Field - The field to change in the instance script. Again, this field needs to be a valid field that has been already defined in the instance's script.
Parameter 2: Target - The target type to use to get the GUID that will be stored at the field index. The value in this field needs to be a valid target type as specified in the reference tables below.
Sets GUID (64 bits) data for the instance based on the target. Note that this will only work when the creature is inside an instantiable zone that has a valid script (ScriptedInstance) assigned.
This function temporarily changes creature entry to new entry, display is changed, loot is changed, but AI is not changed. At respawn creature will be reverted to original entry.
Below is the list of current Target types that EventAI can handle.
Target types are used by certain actions and may effect actions differently
(# Internal Name Discription)
0 TARGET_T_SELF Self cast
1 TARGET_T_HOSTILE Our current target (ie: highest aggro)
2 TARGET_T_HOSTILE_SECOND_AGGRO Second highest aggro (generaly used for cleaves and some special attacks)
3 TARGET_T_HOSTILE_LAST_AGGRO Dead last on aggro (no idea what this could be used for)
4 TARGET_T_HOSTILE_RANDOM Just any random target on our threat list
5 TARGET_T_HOSTILE_RANDOM_NOT_TOP Any random target except top threat
6 TARGET_T_ACTION_INVOKER Unit who caused this Event to occur (only works for EVENT_T_AGGRO, EVENT_T_KILL, EVENT_T_DEATH, EVENT_T_SPELLHIT, EVENT_T_OOC_LOS, EVENT_T_FRIENDLY_HP)
=========================================
Cast Flags
=========================================
Below is the list of current Cast Flags that EventAI's spell casting can handle.
Cast flags are handled bitwise. Bit 0 is Interrupt Previous, bit 1 is triggered, etc.
So for example the number "3" (11 in Binary, selecting first 2 options) would mean that this cast has both CAST_INTURRUPT_PREVIOUS and CAST_TRIGGERED.
Another example: the number "5" (101 in Binary, selecting first and third options) would mean that this cast has CAST_INTURRUPT_PREVIOUS and CAST_FORCE_CAST.
(bit# Decimal Internal Name Discription)
0 1 CAST_INTURRUPT_PREVIOUS Interrupts any previous spell casting (basicaly makes sure that this spell goes off)
1 2 CAST_TRIGGERED Forces the spell to be instant cast and require no mana/reagents.
2 4 CAST_FORCE_CAST Forces spell to cast even if the target is possibly out of range or the creature is possibly out of mana
3 8 CAST_NO_MELEE_IF_OOM Prevents creature from entering melee if out of mana or out of range
4 16 CAST_FORCE_TARGET_SELF Forces the target to cast this spell on itself
5 32 CAST_AURA_NOT_PRESENT Only casts the spell on the target if the target does not have the aura from that spell on itself already.
