Increase attack damage after an attack

[Kurnelia'zooz]

I want to make an passive ability that increase damage to a unit each time it attack that unit again.
Do WC3 have a base ability that do simillar thing? Or I have to trigger it?

Kind of. Incinerate has an effect similar to this but it only stacks a flat damage amount per attack. So you could have the unit deal 15 additional damage with each consecutive attack, but not have each attack increase damage by 5%. It's also not a passive so it needs to be activated (but does have autocast), causes targets killed to explode (even if you set explosion damage to 0) leaving no corpse,d oes not apply life steal, and afaik will mess with other orb modifiers. In short: if this is not workable for you yes you will have to trigger the effect. It would be relatively simple with a damage detection system: Damage Engine 5.4.2.3
