Werewolf Tanking can be difficult on sustain due to all the abilities being Stamina and also needing to block. So for this we use Engine Guardian to help with sustain. Grundwulf would also be a good option. If you are ok with sustain then you could go with Troll King or Earthgore for some additional self healing. If you need none of these, the only other really useful option would be Sentinel of Rkugamz. For Dungeon content, Swarm Mother could be useful for pulling and stacking enemies since you have no chain skill as a Werewolf. Vykosa is good for debuffing enemies.
Main gear set is Tormentor and this is needed so you can taunt the enemies. Without this you are unable to Taunt as a Werewolf.
The second set will depend on what your group needs and what content you are doing. Torug’s Pact works well if you go into Werewolf form on a 2 Handed/Infused/Crusher. Hircine’s will help you to sustain as a Werewolf Tank. Any other Aura sets can be used if needed such as Ebon and Worm. If you are in a group with none Werewolves then Alkosh would be a good set to use also. Frozen Watcher provides a great group buff and only requires you to block to activate it.
Any class will work for Werewolf Tanking but the most useful ones would be Templar and Sorcerer due to their reduce cost passives.
You just need to look at all Class passives that you gain from using a Class and decide which ones you’ll fine most useful as you’ll keep these in Werewolf form. If a passive requires you to have a class skill slotted for the passive then this is not one that will be active in Werewolf form. Most useful class passives for Werewolf would be any Resistance or Reduce Cost passives.
Pretty much any race is playable here. The common races are Nord for Resistances and Argonian or Imperial for sustaining, Orc for more Stamina, Health and Speed.
The best Mundus Stone to use here is: The Atronach for the extra Magicka Recovery for the self healing and sustain.
64 Health is the most useful since your only Heal scales based on Max Health.
As standard we use the Bewitched Sugar Skulls which gives us Max Health, Magicka and Stamina plus more Health Recovery.
You can use regular Tri-Stat potions here.
