I'm using a very simple trigger and a dummy spell for this:
But i think that a missle effect would work better. So i ordered a dummy unit to cast a skill on attacking unit every time the aura guy was attacked. Way too much lag. Anyone knows other method?
Events
Unit - A unit Is attacked
Conditions
(Level of (Aura) for (Attacked unit)) Greater than 0
Actions
Unit - Cause (Attacked unit) to damage (Attacking unit), dealing (20.00 + (20.00 x ((Real((Level of (Aura) for (Attacked unit)))) - 1.00))) damage of attack type Chaos and damage type Normal
Special Effect - Create a special effect attached to the chest of (Attacking unit) using Abilities\Spells\Undead\FrostArmor\FrostArmorDamage.mdl
But i think that a missle effect would work better. So i ordered a dummy unit to cast a skill on attacking unit every time the aura guy was attacked. Way too much lag. Anyone knows other method?
