Season 10 replaces the usual seasonal powers with Chaos Perks. These perks change how your skills work, giving you powerful bonuses but often with a small drawback. It is a system that pushes your build further but asks you to balance risk and reward.
Perk Rarities and Limits
Chaos Perks come in four rarities:
- Magic
- Rare
- Legendary
- Unique
Each character can equip:
- 3 non-Unique perks (Magic, Rare, or Legendary)
- 1 Unique perk
Every class has access to a shared pool of general perks, plus 4 class-exclusive perks (1 of each rarity). These are designed to tie into your class mechanics and open new ways to play. For example, Necromancers can use Defiled Dead, which lets each corpse be consumed twice.
You will find and equip your Chaos Perks in the seasonal powers menu, located in the top right of your character screen. You will only see your class perks and the general pool, not perks from other classes.
How to Unlock Chaos Perks
Most perks unlock through the seasonal reputation track:
- Magic, Rare, and Legendary perks become available as you reach higher ranks in your reputation board.
- Unique perks only unlock after defeating Bartuc in Infernal Hordes on Torment I or higher.
Chaos Perks are not just extra powers; they change how you approach the game. For example, there are perks that can provide huge damage boosts like guaranteed Critical Strikes, but limit your skill usage or add cooldowns. Others improve class mechanics in ways that let you design builds that were not possible before.
