Parallel Execuition?

[JN Arozez]

I have seen many of many NPCs with Parallel Execution but I still don't understand what it does. Somebody please tell me.

when you use a script in a npc, and you activate the parallel execution, the npc dont loses the properties

example: you put a script in the fireball, and you do not activate the parallel execution, then the fireball loses its properties and can not kill enemies, otherwise if you activate the parallel execution, the fireball will retain its properties and if it can kill enemies
