1st skill is okay... don't know why you make a reference to the spear that kill Christ...
Skill 2 shouldn't be a hold + burst damage at the end of the hold, it should be dot over time while holding the unit.
Skill 3, her spells deal spell damage so why does this spell reduce armor. Additionally, this skill provides no other benefits without her other 3 spells.
Skill 4, It's just a super saiyan mode ultimate. Very bland and not much fun for a coder interested in making interesting and fun heroes.
