What's exactly Pure damage and how to do it in Tiggers ? There isn't this option "Pure Damage". Only Spells, Normal, Magic, Fire, Chaos, etc.etc.
and what does it ? Deals more damage or reduced depending on the resistance of the hero or the aarmor type... tell me
Dotaure damage
Warcraft 3:universal damage
Example:I think that if you set attack type to spells it won't damage magic immune units.
Example
Events
Unit - A unit Starts the effect of an ability
Conditions
(Ability being cast) Equal to Storm Bolt
Actions
Unit - Cause (Casting unit) to damage (Target unit of ability being cast), dealing 500.00 damage of attack type Hero and damage type Universal
Universal damage can't be reduced nor amplified.It can only be amplified/reduced with triggers.(Bribe's Damage engine)
