how to detect unit attack damage before attack
So in my situation,
i got a Hero, at random level, taking random item that possible add attack damage to my hero.

so i want make a skill which deal 500% attack damage to target when casted a spell.
How should i count to damage?

Extra Case:"
if i have many many different item to add unit damage (so dun ask me check item condition)
have some skill to add attack damage - from itself or other unit.(so dun ask me also check buff condition)
"
or else got a easy condition can check all item condition or buff condition

add critical strike with 100% chance and 500% damage to your hero when the ability is cast and remove it after he attacked

or you could take his primary atribute, add any attack bonuses he gets from items, add his starting attack power, and then multiply by 5. The problem with this is that the system would have to be huge and you would need to feed it lots of info regarding spicific unit types and item types.

ermmm, i mean i shot the skill like storm bolt got missile arc and reach i cause 500% dmg.
ermmm, u mean that like berserk get effect after cast??

but nvm its not a point.

the point is it easy to cause bug.
for example, the hero been stun before u attack? it gone?
or begin attack i remove it? so when attacked will it mutliply?(use wait action?)
if begin attack i remove it(havent attacked target),but been stunned then no effect d?

or better abandon
