Did it. I still got the same result.Maybe the problem comes from your plugins list. Try to put Skill Core quite high.
A-ha. I found out that's the reason why I keep getting this error.Do you have YEP_Core Engine installed ?
Whenever I perform the skill, it just functions normally.What do you have when you perform the skill ?
The same issue happens.Very odd. Try with Pre Eval conditions and (value >= target.hp) in the if parenthesis
Same issue still happens..Maybe it is a capital sensitive problem.
Try "target.Hp"
I'm kind of starting to give up..I can't see what I miss... Maybe it is a plugin incompatibilty. I can suggest you to try the code in a blank project with only YEP_Core and YEP_Skill Core.
