Whats best skills for bosses? Mage

[Stephencobear]

It works like this:

Ekenta

I use Arcane Shield to stay inside the red circle attacking the boss. And Fireball, Lightning Strike and Curse to attack..

I agree w most but this part
Why use shield on ekenta?

Stay out of red zone and you don’t need any defense skill,
or 1 point in gale mastery negates stun if timed correctly

Point is if you use an attack skill rather than use a defensive skill (shield) where it isn’t needed you are more effective
