Dro'Zakar's Claws

(2 items) Adds 1487 Physical Penetration
(3 items) Adds 657 Weapon Critical
(4 items) Adds 129 Stamina Recovery
(5 items) Adds 129 Weapon Damage, For every bleed effect you have on an enemy, increase your Weapon Damage by 103 against them.

Dro'Zakar's Claws is best used on a Stam Warden because they're the only class in the game to have bleed damage based class skills.

1. Warden's: Growing Swarm
2. Warden's: Cutting Dive
3. Hemorphaging Status Effect
4. Dual Wield: Rending Slashes (or Blood Craze if you need a heal)
5. Dual Wield: Rend (Ult)
6. 2 Hander: Carve
7. 2 Hander: Stampede (With Maelstrom set equiped)
8. Fighter's Guild: Barbed Trap
9. 5 Piece Set: Pestilent Host or Pillar of Nirn or Savage Werewolf or Unleashed Terror.

9 applied bleed effects for a possible +927 weapon damage from Dro'Zaker's Claws on the 5 piece alone. This would be my recommendation.

Noteworthy set instead of Dro'Zakar is:

Aegis Caller

(2 items) Adds 129 Weapon Damage
(3 items) Adds 129 Stamina Recovery
(4 items) Adds 129 Weapon Damage
(5 items) When you deal critical damage with a Martial melee attack, summon a Lesser Aegis for 11 seconds. After 2.5 seconds, the Lesser Aegis spins its blades, dealing 502 Bleed Damage every 1 second. This effect can occur once every 12 seconds and scales off the higher of your Weapon or Spell Damage.

Aegis Caller is a very strong pve aoe bleed set that will crit next patch. The damage per second on live with 6k weapon damage is about 3.5k a second. Note, it's not a bleed applied to the enemy so it does not buff Dro'Zakar's Claws, therefore you'd probably want to do one or the other.

For comparison sake on live with 6k weapon damage:

• Pillar of Nirn = 5k bleed damage upfront in 2.5m radius, enemies hit take 27k bleed damage over 10s.
• Pestilent Host = When an enemy dies with a poisoned effect on them, apply 46k bleed damage over 10s to the nearest enemy within 12m.
• Savage Werewolf = Light/heavy attacks cause enemies to bleed for 1.9k damage every 1 second for 4 seconds.
• Unleashed Terror = Dealing direct damage with a pull, leap, teleport, blink or charge ability causes the enemy to take 16k bleed damage over 10s. This will give you the hemorphaging status effect too, which is about the same damage per second, 6.4k over 4s, but since it constantly refreshes, it's like the set gives you a 32k dot.

Savage Werewolf is probably the weekest dot of the bunch, but the easiest to apply. Pestilent is probably the strongest, but the hardest to apply. Pillar of Nirn and Unleashed Terror are close to the same damage, however Pillar of Nirn may provide more seeing as Hemorphaging uptime could be high with your other sources. It is on a 10s CD that has a small aoe effect that can miss your target though, while Unleashed Terror is a 10s CD PER target instead and easily applied via Stampede that lines up easily with Mercilous Charge. Unleashed Terror also gives you guaranteed, 100% uptime on Hemorphaging instead of trying to rely on RNG making it a great bonus for a set like Dro'Zakar's Claws.

Pillar of nirn has been low key amazing for awhile, and I believe it will be able to crit next patch. I would definitely pick this up. Blooddrinker buffs bleeds by 20%, another good one, although I feel deadly strike might be better because you are going to have some non bleed damage sources.

Bleeds on a nightblade is interesting, but I guess you could go dual wield front and two handed back bar with bloodthirst and blood craze and the dual wield ultimate. Carve on the backbar with barbed trap.
