Use a trigger so whenever he cast a spell create a dummy, set the dummy life=life of casting unit, then give your Hero damage based on procentage life missing.
You cannot set a hero damage..... You have to have a skill thatis base on damage increase of claw of attacks to do it...... So i suggest make 3 ability on claw of attack..... each having 10 levels... on the 1st.... 0,1,2,3..... and on the 2nd.... 0,10,20 and onthe the 3rd.... 0,100,200,300.. Then use triggers to check with the mathematic function Modulo.... I dun rly have the tmie to give you the real triggers....
you can set the hero's damage via jass... get a system called Bonus, or UnitProperties... (not sure which one) its very easy to use... and you can increase/decrease the damage from that
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
I will be AFK for a couple of days you guys hold down the fort while I am gone. I will be checking in on my phone but that will severly limit me. Be back saturday!
