Vengeance Demon Hunter Tank Gems, Enchants, and Consumables — Battle for Azeroth (BfA) 8.2.5

You should use Leviathan's Eye of Agility in one socket, and Quick Sand Spinel (or the cheaper Quick Owlseye) in all other sockets.

You want to use 2 different enchants on your gear because you gain more stats from this method than stacking 2 of the same one.

The reason we do not have Enchant Weapon - Deadly Navigation listed for DPS is that the actual DPS gain on the enchant and Critical Strike in general is extremely random, and you gain more survival from the other stats. It is not recommended to gem or enchant Critical Strike or aim for the stat on gear.

Greater Flask of the Currents (DPS) or Greater Flask of the Vast Horizon (Survivability) should be used for raids, along with Superior Battle Potion of Agility as your potion of choice.

Abyssal Healing Potion can be used along with Healthstones as they do not share a cooldown.

You should eat from the Famine Evaluator And Snack Table when possible, and otherwise Haste food ( Baked Port Tato or the cheaper Swamp Fish 'n Chips).

Note that you must change spec to Havoc at the moment when you eat the food in order to avoid getting a Stamina buff. That said, the Stamina buff is also viable.

If you can afford it, you should use Battle-Scarred Augment Runes to increase your primary stat. Since there is a finite amount of these runes available, you should make sure to use them wisely and to stock up on them for when you need them.

War-Scrolls provide weaker versions of the class buffs, which is helpful in dungeons if you do not have a class that provide it.

1. War-Scroll of Battle Shout
2. War-Scroll of Intellect
3. War-Scroll of Fortitude
