All Boss Powers in Diablo 4 Season 8, and how to get them

Diablo 4 Season 8 is going to feature some truly incredible boss powers for players to harness. That’s right, if you’ve ever wanted to use the Chest Beam of Wandering Death, or Ashava’s Poison Breath, you’ll have these at your beck and call, providing you can defeat the Apparition Incursion that hides them.

Thankfully, they will be up essentially 24/7, and each one features two bosses out of a pool of 10 at random, so eventually, you can unlock them all.

Many of these new boss powers are unlockable at any difficulty level too, in Diablo 4 Season 8. However, some exceptional powers require you to reach at least Torment I, but it sounds like they’re worth it.

All unlockable boss powers in Diablo 4 Season 8

Diablo 4 Season 8 introduces Apparition Incursions, which can be seen on the world map, and from these, you unlock new boss powers. These boss powers are equippable, similarly to every other season in the game, with some twists. There are 24 in total, which are unlocked the first time you defeat these bosses in certain situations.

Each power also has two sides you can activate — a Main Power and a Modifier Power. You can have one Main Power equipped, and three Modifier Powers equipped at any given time. Below is a list of every power we’ve seen so far, and what their main/modifier power is. It will also feature the unlock requirement, if there is any.

Please note that an asterisk (*) denotes a boss that requires the Vessel of Hatred expansion.

How are boss powers unlocked in Diablo 4 Season 8?

These fights look interesting, and also reward you with amazing new powers (Image via Blizzard Entertainment)

The 24 new boss powers are unlocked by defeating specific targeted bosses in Diablo 4 Season 8 for the first time. This can include, as seen above, the new Apparition Incursions, World Bosses, and Boss Ladder fights. That means, across the whole spectrum of the game, you can unlock incredible fresh powers.

The way the Apparition Incursions work, is when you come to one, you’ll have to go through a mini-boss rush. You’ll need to defeat some apparitions, and this includes two bosses from a pool of ten. After you defeat those, you’ll have to face the mini version of Belial, Lord of Lies — who is also the Exalted Pinnacle boss going forward.

Defeating these foes for the first time grants you the boss power, which you can then equip in the seasonal UI. It will be genuinely interesting to see which of these winds up being used the most in builds going forward.
