Shadowcaller (Support) - Group Dungeon / Static Dungeon

Combo:

Use your E within a moment you see the Tank is using "Air Pressure" as it takes a while for your skill to drop. Make sure you're targeting in on top of the Tank to hit all the mobs. Your other priority is to use R to help the healer with cooldown and helmet to drop mana for everyone.

Words of Wisdom:

Make sure to be the first one to use your jacket skill and if you see overlap, point out that you'll be the first one to use it. You may also help tank by bringing in more mobs if they are too far away or end up running away but do it based on the situation and demand.

Any Leather and Cloth shoe work.
