can dummy units cast spells?

can dummy units cast spells?

ive made this dummy unit a cloud that follows heroes im trying to make it so when the hero attack a unit the cloud zaps the same unit. can anyone help me plz.

thx

set the attacked unit as a unit variable and a trigger:

events: unit is attacked
conditions: attacking unit is 'hero
attacked unit is 'unit var'
actions: order dummy to attack once 'unit var'

yer but i wanna the cloud to zap that targeted unit

then give it a chain lightning ability or sumthing (i dont rly know what u mean by 'zap' )
