I noticed theres a bug "element" whenever you hit certain enemy, it will heal them instead. I think it was because of the skills's enchanted weapon element. I suggested avoid using those skills. If you really wanna use element, preferably using the weapon with such attributes. Or maybe element bracelets? Idk didnt test them yet. But if you accidentally use those enchanted skills, simply runaway from the battle and reload saved game. I think someone had mentioned this before, so I thought a new update would fix it. But, unfortunately it is not.
