Axe Swing
Inflicts damage to 1 unit. Nothing interesting or hard here, any healer can offset the damage done by the basic attack from the boss since it’s pretty low.
Whirlwind
Deals damage (medium to high depending on your units, level and gear) to 3 targets.
She becomes immune to 40 instances of damage, if you fail to remove these 40 “instances” you will be stunned for 7 seconds. This is pretty annoying but also easy to overcome as long as you have multiple damage dealers on your team.
10 second cooldown on this skill, meaning you will need to bring multiple DPS units to deal with this multiple times during the fight.
Knockback Immunity
A passive you don’t have to worry about at all since we barely have any units in the game that can move bosses.
