Get this ability in the version 8.22 forum, but I'm using version 10x and I'm not able to balance the damage and the damage. Could someone help me set up? wanted a damage between 300 - 500 (in player) a player who met these criteria for having a skill of at least 100, a solar axis and level 200+. Another help I wanted was the following ..

I wanted a damage that takes on all players and players.
