some help with passive possesion skill

[talshiboli]

hey guys,one of the chars. in my map is a confessor (those of you who have read the sword of truth know what im talking about,for those who dont it just means she can take control of enemy units)
anyhow.....I thought Ide give her a passive ability that grants a set chance to convert an attacking enemy unit but im not that great with the trigger system and theres no base ability I can think of that could do this...
if anyone has ideas I would love the help

wat about charm ?

 

[talshiboli]

Yes,but the question is how do I make it passive...
I thought of using a dummy spell of some sort but I dont know how to make the trigger system calculate chances of activition every time im attacked...

to be extra clear the idea is this - for eac time the confessor is attacked by a melee there is a (say) 3% chance that the attacker will be converted and fight by her side.

Use this condition.
