Probably the hardest part about finding a good werewolf build. Since you can´t really customize your skill loadout too much, you´re very dependent on what gear you use. But a few sets that you can´t go wrong with:

* Shacklebreaker
* Automaton
* Bonepireate/Hulking (max stamina sets)
* Fortified brass (as mentioned above): Another option is to run protective jewellery.
* Impregnable (both medium and Heavy)
* Plague Doctor/Green Pact (max HP sets ot boost your heal)

* Clever Alchemist/Ravager/7th Legion/Fury/Veiled Heritence (weapon damage sets)

General advice is to test as much as possible and find what you like to use

A common thing I see when people gear out a werewolf is that they focus way too much on max stamina and high weapon damage. While these two stats contributes to your damage output as a werewolf, that´s about it. On a non-werewolf stamina build, these two stats will also add to your healing (Vigor and Momentum). Running around with 50k+ stamina and 8-10k weapon damage is in my opinion pointless unless you´ve dedicated supports with you. Also, putting too much effort into these two stats will lead to you having less Health and more trouble with magicka and stamina sustain.

What you should prioritize in my opinion (for people that can´t rely on a healer or support):
1: Max Health: Somewhere between 25-30k HP will give you a good selfheal potential in werewolf form.

2: Max Magicka and magicka recovery: While might look like a strange thing to focus on as a werewolf, the moment you run out of magicka to use Hircine´s Rage/Fortitude, is the moment you´ll drop dead. How much you should aim for is up to personal preference. But being able to use Hircine´s Bounty 3-4 times in a row without running dry on magicka is a good mark to aim for.

3: Weapon Damage/Max stamina: Werewolfs has a lot of "in-built" damage through their passives, which means you can usually build for more defense, but you usually need to focus on some damage to kill people. In terms of weapon damage, the lowest I run with is around 3-3,5k. This is very low, but since werewolfs has easy access to bleed damage and defiles, you don´t need to stack weapon damage. If you´re able to hit 4-4,5k weapon damage you´re able to kill almost any target you face, with exception of pure healbots and Health tanks. For max stamina, stack as much as you feel comfortable with. For me that´s around 40k (give or take a 1-2k).

4: Physical-/spell resistance and crit resistance´.

5: Stamina recovery: Werewolf skills are costly and you can´t afford to spam them or you´ll run dry of stamina very fast. Even a build stacking 50k+ stamina will deplete its stamina that way. Werewolfs best DPS tool is light attacks. Use your skills carefully and don´t spam piercing howl unless you really, really need to burst someone down quickly. Learning to utilizing Heavy attacks for sustain gives you the option to avoid investing into stamina recovery (and go for more damage). And if you use Ferocious Roar (sets enemies off-balance) and Heavy attack on off-balanced targets, you can twice the amount of stamina back (in Heavy armor that´s around 10k stamina back on a Heavy attack)
