Bosses and BOSS maps
Find the 26 names in the official wiki’s Bosses category and distinguish them from the 18 BOSS-map names. Some arenas contain several named opponents, waves or multiple segments. Open the researched encounter pages for objectives, enemy health context, rewards and historical changes rather than treating every arena name as one boss.

Names and category membership come from the wiki snapshot. A dash marks a field with no recorded value in this directory. Mechanics refer to the indicated action, hit or cooldown rather than a calculated damage-per-second ranking.

Choose an encounter by its objective
Beta puts three Beta Devs in one arena. Uncertified mixes enemy waves and named bosses. Etherealgaze advances through Trees, Roots and a final target. These differences explain why one “boss difficulty” number would omit the objective that a party actually needs to complete.
Etherealgaze is the newest researched map addition in the v2.4.0 notes, while Specimen 9 is marked removed in the same update. A historical detail page remains useful for identifying old footage, but its existence does not mean the encounter is currently offered. Perfect Run uses a private-server switch with separate reward conditions; the rules and blacklist pages below keep those requirements visible.
