a Spell to give +damage = <an atributte of caster heroe>??

Ok i didnt found a solution with the gui so anybody knows something in jass or maybe gui to make a spell that gives damage = to the INT,AGI or STR of caster heroe???. I dont want only to do more damage but to show those green number of more attack that for example give the item attack bonus ability. Any ideas???

These methods can add bonuses to a stat, though the demo code only does it for Attack, Armor, HP, mana it can be easily modified to add things like Str, agi,int.

Ok gonna see if it works thankz weaadar
