Who cares about Season 7’s Witchcraft Powers or Artificer’s Stone, when you got Boss Powers in Diablo 4? Season 8 of Blizzard Entertainment’s iconic RPG has players perked up about the new features in D4. The Boss Powers in Diablo 4 are special abilities you get by defeating bosses, and they give your character passive effects that can change how your skills work. If you played during the Season of Witchcraft, Boss Powers will feel familiar.
But if you missed the tutorial or just want a clear guide, here’s everything you need to know about Boss Powers in Diablo 4—how to get them and how to upgrade them.
How to Get Boss Powers in Diablo 4

Boss Powers in Diablo 4 come from defeating bosses, but the way you get them depends on the type of boss and the rarity of the power. Here’s a simple breakdown:
- Magic Boss Powers: These drop after you defeat Apparition Incursion bosses. You can get these on any difficulty. There are 10 Magic Boss Powers in total.
- Rare Boss Powers: These come from killing Lair Bosses, World Bosses, and the lesser form of Belial. There are 9 Rare Boss Powers.
- Legendary Boss Powers: These are the rarest and drop from high-level bosses in Torment I difficulty and above. Some bosses that drop Legendary Powers include Lilith, Duriel, and Belial. There are 5 Legendary Boss Powers in total.
If you’re just starting out, the best way to get Boss Powers is by grinding Apparition Incursions. These are easier and give you a good chance to collect Magic Boss Powers before you move on to hunting tougher bosses.
How to Upgrade Boss Powers

Upgrading your Boss Powers is simple but requires a special currency called Spectral Ash. You earn Spectral Ash by defeating enemies during Apparition Incursions and other related events.
The cost to upgrade depends on the rarity of the Boss Power:
- Upgrading a Magic Boss Power from Rank 1 to Rank 2 costs 15 Spectral Ash.
- Upgrading a Legendary Boss Power from Rank 1 to Rank 2 costs 25 Spectral Ash.
Because of this, it’s smart to start grinding Incursions early in the season to gather enough Spectral Ash for upgrades.
To get the most out of Boss Powers in Diablo 4, focus on grinding Apparition Incursions early to collect Magic Boss Powers and Spectral Ash. Then, challenge tougher bosses to get Rare and Legendary Powers. Keep upgrading your powers to make your character stronger and more versatile.
