Blood Death Knight Tank Gems, Enchants, and Consumables — The War Within (11.2)

You should use a Culminating Blasphemite in your first available gem socket, and fill every other with Versatile Ruby.

In practice, these guidelines are largely down to how enchants do not compete over primary stats, merely secondaries. As a result, the gearing stat priority is applicable and can be simply followed: Versatility as a good default, or whatever sims the highest for you at the time for damage. You can find more information about this on the stats page of this guide.

Use Flask of Alchemical Chaos as a general-use Flask. If you prefer to have a simpler flask that provides a single secondary stat Flask of Tempered Versatility can be used instead.

If you are actively pushing Mythic+ keys and gold is no issue to you, it is possible to gain a significant amount of value on specific encounters by swapping phials mid-run. If you intend to do so, you should plan your swaps ahead.

The only flask that is worth noting on this is Flask of Tempered Versatility; while it is less raw stats than Flask of Alchemical Chaos, if you absolutely need to be able to rely on it for damage reduction (particularly when paired with a Tempered Potion), you should temporarily swap to it.

Algari Mana Oil as a safe defensive and offensive option. For raw damage, you should sim between Algari Mana Oil and Ironclaw Whetstone / Ironclaw Weightstone.

Your default potion for all situations is Tempered Potion. Flask of Alchemical Chaos may temporarily alter the secondary stats it provides as a result.

You should use Invigorating Healing Potion for in-combat healing. Healing potions do not share a cooldown with Healthstones, so you can use both independently if you can access a Warlock.

Use The Sushi Special / Everything Stew as your food buff of choice if a Feast is not available.

If a Feast of the Midnight Masquerade / Feast of the Divine Day is available, use this instead.

In addition, if you can afford it, you should use Draconic Augment Runes to increase your primary stat. Since there is a finite amount of the consumable runes available, you should make sure to use them wisely and to stock up on them for when you need them.

Through the Patch 10.2 Emerald Dream Zone and its Dream Wardens Faction, you can also obtain the Dreambound Augment Rune, which is permanent!
