Entry Requirement

Must discover in zone; optional

Chambers are optional challenge arenas in 33 Immortals found throughout rebellion zones such as Inferno, Purgatorio, and Paradiso. These instanced arenas spawn waves of enemies under specific conditions and reward players with powerful loot upon completion. Chambers offer high-risk, high-reward opportunities and are ideal for teams looking to power up mid-run.

Overview

Chambers are self-contained rooms or arenas that activate once entered. Upon activation, players are locked in and must defeat a series of enemy waves. These waves escalate in difficulty and often feature elite Monsters, status-inflicting enemies, and environmental hazards. Successful completion grants valuable rewards including Relics, Fragments, and Chest Keys.

Encounter Types

Each Chamber may vary in mechanics, but generally fall into one or more of the following:

• Wave-Based – Fight off multiple waves of enemies under time pressure
• Timed Survival – Survive a set duration while avoiding hazards
• Boss Variant – Face an elite enemy with mechanics not found in the open zone
• Modifier Chambers – Include special conditions (e.g., low visibility, movement debuffs)

Rewards

Chambers are among the best sources of high-tier loot in a rebellion run. Upon successful completion, rewards may include:

• Powerful or rare Relics
• Fragments used for relic rerolls or upgrades
• Chest Keys to access locked loot throughout zones
• Large drops of Souls and secondary currencies like Bones or Dust

Strategy

• Enter with a full team, if possible, to maximize clear speed
• Conserve Special Abilities and Co-op Powers for elite waves
• Make use of crowd control effects like Slowed and Stagger
• Communicate before entering — many Chambers cannot be exited once started

Visual Indicators

• Chambers often appear as side-path portals or sealed gates
• Glowing symbols, ambient effects, or icons may indicate a Chamber’s type
• Some require triggering a specific event or defeating a miniboss to open

Optional but Rewarding

• Chambers are entirely optional and not required to progress through zones
• However, clearing Chambers can drastically improve your Loadout for boss fights
• Consider clearing early ones for momentum and saving difficult Chambers for later runs

Summary

Chambers in *33 Immortals* are where rebels prove their worth beyond the main path. These crucibles of chaos offer treasure to those brave enough to enter — and punishment to the unprepared. When faced with a Chamber, one choice remains: step in... or be left behind.
