Stats will always vary and change based on your gear, as stats can lose a lot of value once you reach a certain threshold. The best way to always be sure that you are using the best gear is to use Raidbots and check the Top Gear and Stat Weights options. You can learn how to sim your character by looking at the ‘How to Sim Your Character’ section.
Strength > Mastery > Haste > Crit > Versatility
Strength > Mastery > Crit > Haste > Versatility
Strength - As with most classes in Shadowlands, primary stat is always the best. It's a simple, straightforward throughput increase to every aspect of Unholy Death Knight.
Mastery - This increases your Shadow damage and the damage of your Minions. Most of Unholy Death Knight's damage comes from Minions, which makes Mastery your best secondary stat. It also scales very well in AOE, as most of your AOE abilities do Shadow damage.
Haste - This, along with Crit, will be changing a lot based on what gear and Soulbind you are using. Haste is better than Crit for Single target; however, it will fall off a bit in AOE as Mastery + Crit will scale better in those scenarios.
Crit - This stat usually is worse than Haste for single target. However, once we have a good amount of Haste, Crit will often pull ahead, and you will see yourself wanting Mastery + Crit items instead. In AOE, Crit is one of your best stats and should be prioritized over Haste. Crit will also gain more value when using Bonesmith Herimir, as it will increase the rate that Herimir's Arsenal: Marrowed Gemstone stacks up. If you don't have many crits, it will take a while to stack up and might not proc until all your cooldowns are over, which is terrible.
Versatility - Quite a boring stat honestly, it just gives you a flat damage increase and some mitigation. It doesn't interact with the Unholy Death Knight kit and is usually just a last resort stat to pick up.

Mechagnome: Primary stat (Strength) is the best stat for Unholy Death Knight, so gaining +40 strength after the first 50 seconds of a fight with Combat Analysis is very strong, making Mechagnome one of the best races.
Human: Humans are generally a solid option for all classes in the game, providing an additional 2% to all secondary stats with their racial The Human Spirit. This makes Humans a very good race for Unholy Death Knights.
Gems and Ring enchants heavily depend on your current stat weights and will often fluctuate depending on your current gear. I will list the enchants and gems you will generally want to use, but you should always check on Raidbots to see which are currently the most valuable for you.
- Back: Enchant Cloak - Fortified Avoidance - Avoidance is the best option for progress, mitigating a lot of damage on certain fights
- Chest: Enchant Chest - Eternal Stats - Depending on gear, this will edge over Enchant Chest - Eternal Skirmish on Single target and is definitely more valuable on AOE/Cleave encounters
- Hands: Enchant Gloves - Eternal Strength
- Weapon: Rune of the Fallen Crusader - Death Knight Runeforges are better than Shadowlands Weapon Enchants, and for Unholy, this Runeword is the best in both Single target and AOE situations
- Enchant Ring - Tenet of Mastery - +16 Mastery
- Enchant Ring - Tenet of Haste - +16 Haste
- Enchant Ring - Tenet of Critical Strike - +16 Crit
- Masterful Jewel Cluster - +16 Mastery
- Quick Jewel Cluster - +16 Haste
- Deadly Jewel Cluster - +16 Crit
Food: The best food comes from a Feast of Gluttonous Hedonism, which will give you +20 Strength; however, these are usually placed down for an entire raid or party as they can be pretty expensive. So if you want your own food, you can eat Iridescent Ravioli with Apple Sauce for a +30 Mastery buff.
Flask: Spectral Flask of Power
Chest Buff: Heavy Desolate Armour Kit
Combat Potion: With the way things are currently balanced, Potion of Spectral Strength is the best potion to use for both Single target and multi-target scenarios.
