Function: AddProc(Spawn, Type, Chance, Item, UseAllSpellTargets)
Description: Add's a proc for a Spell and calls function proc when proc succeeds.
Parameters:
Spawn: Spawn - The spawn or entity involved.Type: int8 - See PROC_TYPE defines.Chance: float - Chance of proc 1-100.Item: Item - An item reference.UseAllSpellTargets: int8 - Default is 0, when set to 1 all spell targets will apply the proc not the Spawn
Returns: None.
Original spell targets: When this function uses a spell's target list, it snapshots references to the originally selected actor allocations. It skips unavailable or departed targets instead of selecting another actor with a reused runtime ID. Accepted actors remain physically retained through the active protected callback, including Lua errors; saved userdata and target records do not keep them alive between callbacks. Explicit Spawn arguments retain their existing selection behavior. See Lua actor lifetime.
