Use preparation rules that remain useful across bosses while encounter-specific facts are independently verified.
In this guide
The current official publisher page lists 12 bosses and 36 enemy types. Until each encounter has been verified independently, this hub focuses on preparation rules that remain useful across mutated guardians instead of inventing names, phases, or drop tables.
Prepare the loadout
Bring a plan for sustained pressure, recovery, and any enemies that may compete for space during the fight. A build that only works during a perfect stationary window is fragile. Test reload safety and resource demands before entering a boss room.
Review the weapons overview and Charms guide when the build lacks consistency.
Read the arena
Use the opening moments to identify safe lanes, hazards, and places where the camera or environment limits awareness. Move early instead of waiting until an attack fills the remaining space. Preserve enough distance to read the boss without separating from the team.
Protect recovery windows
In co-op, call out pressure changes and protect players who must reload or recover. Do not spend every defensive option on the same attack. If the fight repeatedly ends in one phase, change positioning or survival tools before adding more theoretical damage.
Continue with the co-op guide and suits and skills.
Boss attempt review
After a failed attempt, classify the failure before changing the build. Changing damage when the real problem is positioning wastes the information gained from the fight.
| Failure type | Evidence | Next adjustment |
|---|---|---|
| Arena reading | Damage arrives from off-screen or an occupied escape lane | Change camera discipline, spacing, and movement timing |
| Add pressure | Extra enemies remove safe reload or recovery time | Reserve control tools and assign a player to clear space |
| Resource failure | Ammunition, healing, or key skills run out too early | Improve efficiency and stop spending recovery on avoidable hits |
| Damage window | The team cannot maintain safe pressure | Choose more reliable uptime instead of a fragile burst setup |
| Team collapse | Several players use recovery tools at once or separate | Establish callouts, lanes, and staggered defensive resources |
A pre-fight checklist
Confirm that the loadout can damage while moving, reload without requiring a perfect stationary window, and handle another threat entering the arena. In co-op, name the player responsible for group control and agree on a simple regroup direction. Keep one recovery option available until the team understands the next phase or pressure change.
The publisher confirms 12 bosses and 36 enemy types, but the official overview does not list every boss, phase, arena, or drop. Publishing invented names or copied unverified drop tables would be worse than leaving the list incomplete. Individual encounter pages should be added only with current-version screenshots or reproducible notes.
