Double Attack Ability?

[kelogsloops]

Okay I want to make an ability like this.

Gives a chance to fire an extra shot at an enemy target. |n|n|cffffcc00Level 1|r -13% chance to fire an extra shot which deals 60% damage.
|n|cffffcc00Level 2|r - 15% chance to fire an extra shot which deals 70% damage.
|n|cffffcc00Level 3|r - 17% chance to fire an extra shot which deals 80% damage.
|n|cffffcc00Level 4|r - 19% chance to fire an extra shot which deals 90% damage.

The thing is, I can't think of a way to make it deal the DAMAGE of the unit, plus the percentage thingo :< This is my trigger so far.

> Trigger - Add to (This trigger) the event (Unit - Target Takes damage)

This might just add the same unit event several times...
It should definitely not add it to itself either.

> Set Value = (Damage taken)

Use that on some other trigger instead, that gets all those damage events.

how do you determine the % damage?u used (value x 0.60)..that 0.60 means 60% isit?

 

[kelogsloops]

burt hows it meant to get the damage taken value if i dont set it in THAT trigger? :<

and and yeah x0.60 its 60% of the damage taken.

What about using crit and giving it projectile art?

 

[kelogsloops]

Hmmmmmmmmmm...... maybe that works. wait but thats not an EXTRA attack :<

 

[Slapshot136]

i think it would work if you make an orb affect with critical strike as the ability inside the orb effect, the orb having the % to cast and the crit being a 100% chance to deal the damage

use orb of slow(item) ability and in it set the slow to searing arrows with no damage and your projectile art, then set in the orb of slow ability the chances.

But its not a seperate attack is it D: its still one attack cause of the crit.
