However,the best place to find the Unique weapon is from the rewards of Infernal Hordesintroduced in Season 5 worlds. The Aether you collect from Hordes helps unlock chests containing rare gear after defeating multiple enemy waves and bosses.
The harder you make an Infernal Horde, the more likely the Umbracrux Dagger will appear as lootwhen you tear through a round of enemy waves.Hellbreaches inDiablo 4on lower-difficulty World Tiers can help you prepare for tougher Hordes, which only exist on World Tiers 3 and 4. While the odds of getting this specific Dagger are low, you may always try to do Hordes again to farm other valuable rewards.

Usually, the chests from Infernal Hordes reward your character with items pertaining to their class. So, if you challenge the Hordes with a Rogue character, you have a higher chance of getting the Umbracrux Dagger.
Pursuing Season 5’s main storyline will put you on a path leading to the Dagger since you have to complete seasonal content as quests. Following missions tied to this season’s events could be a great way to earn the Umbracrux early, especially if you already have a strong build. Try to explore every side quest new to the game to see if you can get a lucky drop from something outside of Infernal Hordes.

The primary ability of the Umbracrux Daggercomes from Subterfuge skills, meaning that it won’t mesh well with everyRogue build inDiablo 4.

These Totems can be targeted by enemies to take damage, but any damage they receive is reflected on surrounding enemies with a 30% effectiveness.

Youcan only have two Shade Totems activeat once, limiting how much damage reflection you can create against enemy hordes. Thankfully,this ability from the Dagger counts as a Trap skill, so it can be boosted by any other items that benefit those abilities. Trap builds are typically not as strong as others of the same archetype, so this item is an incredible buff to an underrated path for Rogue characters.

Having this weapon can make you deadly against Infernal Hordes, though it won’t help you much against enemy players in PvP. This item is best used alongside friends, especially with Necromancers who can add allies of their own to the Shade Totems you summon. The Umbracrux Dagger inDiablo 4does not require any input from you, making it easy to get Totems as you attack enemies consistently.
