cant find fan of knives spell cast in triggers

[13lack.1)ragon]

I have a tower that attacks using fan of knives. I know that chain lightning works this way with this trigger:

Event: A unit is attacked

Condition: Attacking unit = to bronze dragon

Actions; Unit - order (attacking unit) to Orc Far seer - Chain Lightning (Attacked Unit)


Is it possible for me to be able to make a tower autocast fan of knives? Ty for any help

Yeah, but instead of Issue Order Targeting a Unit or whatnot, it's Issue Order With No Target. Look for Night Elf Warden - Fan of Knives.
