How can i set the dmg of a skill based off the casting unit's attack damage?

well, How can i set the dmg of a skill based off the casting unit's attack damage?
that's all :], well i mean how can i detect a unit's attack damage?.

You can't, unless you hard-code the caster's attack damage into the spell (which can be tricky if the caster is a hero and there are many items and spells in your map that modify attack damage).

in the knew, small Gaia's retalitation Rpg (i misspelled it i think),
they have done it, and works perfectly fine :\.
i just hoped i can do some thing like that, oh well guess my spells will be based of strenght

if you use something like BonusMod to do _all_ attack damage bonuses in your map, then you can mathemagically find out a unit's attack damage quite easily. You still have to hardcode the casters base damage stats, and primary attribute if it's a hero.

Take a unit's base damage, add the bonus from BonusMod, add the amount strength/int/agi effect it, and you're done.

Sure it is possible, but we are trying to say is that it is hard, refer to EF's post for more info.

try searing arrows without bonus damage. it deals the caster's attack damage + bonus damage. if bonus damage == 0.00, you get the caster's attack damage only.
use a damage detect system to detect when the target takes damage with the buff, and multiply/play with the damage in a damage response function.

since its an 'attack-autocast' spell, you might want to trigger something to prevent it from being autocasted if you want to use it just as a spell.
