Yeah I guess I didn't explain it, it basically if you check the Re-Roll Elements next turn you will roll for a random element, there is supposed to be some that are more or less effective to other elements, but I couldn't quite get the effectiveness text to show consistently. Each time you defend/attack the enemy does the same and each roll the dice and get the damage roll, it's a little buggy, might try to fix after jam period. Anyway my bad, thanks for the comment.
