Essential Skills for this Trial:
When Tanking Lokkestiiz you can range Tank, you do this by standing at the back of the arena and cast Defensive Stance to reflect the damage back at the boss. You shouldn’t use any shields that absorb damage, use this skill that reflects it.
On Yolnahkriin you’ll need a pull/chain for the Flame Atronachs.
On last boss Immovable can be used, mainly on hardmode so you can stand in a negate without being stunned during the breath mechanic.
Off Tanks will find Race Against Time useful on the last boss hardmode when dealing with the statues. Efficient Purge is also useful on Lokkestiiz hardmode to remove the debuff from your group members.
