Okay I managed to do it.. so i'll try to explain
First i created a State named Sentence that is 100% applied by the skill Coup de Grace
than...
I created a comon event for each # enemy named Paralize
Paralize 1 switches Paraliz1 = ON if enemy #1 is afected with paralize
Paralize 2 switches Paraliz2 = ON if enemy #2 is afected with paralize and so on....
after that I created one comon event for each Paralize event and named them as CdGrace1, 2, 3 and so on
CdeGrace1 is like this
• if paraliz1 is ON
• if enemy#1 is affected by Sentence
• Change enemy state: #1, + Dead
• end
so if paraliz1 is on cuz enemy#1 is affected by paralize spell
Coupe de Grace will apply Sentence, and if #1 is affected by Sentence, he will die
for the rest of the troop
CdeGrace2 is like this
• if paraliz2 is ON
• if enemy#2 is affected by Sentence
• Change enemy state: #2, + Dead
• end
and so on....
The Spell Paralize must call all Paraliz comon events, for me the amount is 4, cuz the max troop size for my game will be 4
so Paralize wlll call comon event Paraliz1, Paraliz2, Paraliz3 and Paraliz4
The skill Coup de Grace will call all 4 CdGrace comon events and apply Sentence with 100% rate
So every enemy affected by paralize that is Hit by Coup de Grace, will die
Hope it helps someone
