*IMPORTANT*: HAVE AT LEAST 40K HEALTH
This is key in order to boost your damage and tankiness

Pros:
14% of all base damage reduced just with Ice fortress activated (add armor, block and minor maim during fights)
Almost armor cap
Constant AOE damage + AOE burst
2 AOE stuns
High chances of applying minor maim (15% damage reduction, from chillied status) to all enemies nearby
Good healing + shield (all scaling on max health or NOT scaling on max magicka/stamina)
Amazing against melee enemies
Great resources recovery (especially with 5 piece set of BLACK ROSE)

Cons:
No gap closer other than bird of prey
Low max stamina (I suggest have at least 15K) and used only to CC break/block/run

Use 5 piece set of either black rose or Aspect of Mazzatun (Trainee works as well)
use other piece that give magicka/stamina recovery and perhaps health (up to 40K)

Always keep your 2nd bar slot buffs (+ bird of prey on bar 1) active and cycle through spiked bone shield with heavy attacks or block (depending on severity) when need to heal up further (if ultimate bar 2 is not up or need to use ultimate bar 1)
