Observed boss directory

Boss Where it appears in the footage What to check before fighting
Ash Captain Story boss at stage 10; also a raid selection tab Which mode you selected; do not reuse Story stats for raid rewards.
Storm Titan Server raid panel Join window, Normal/Hard selection and reward thresholds.
Spire Keeper Dungeon room/boss panel Party state and remaining lives.
The Eclipse King Dungeon panel The current room and party’s ability to sustain a run.
Iron Colossus Guild-war target Guild progress tier and personal qualification text.

This is an observed directory, not a complete bestiary. We do not publish HP, weaknesses or a move sequence for a boss unless the exact mode and state are supported. A boss-stat template is not evidence that a weakness exists.

Pick the matching mode guide

Raids explains the server join window and reward milestones. Guild wars covers the tiered target panel. Progression helps when a mode is still locked. Story and Tower are also visible as distinct mode tabs; do not confuse a Tower floor with a Story stage.

Build around what you can observe

Watch whether your front survives until recurring abilities trigger and whether attacks reach the target that matters. Read the specific card’s ability: Overlord’s execution explicitly applies to non-boss foes, so it must not be promoted as a boss execute.

Use combat for role and position terms, best team for a lineup checklist and the source finder for documented gear sources. No unverified boss-specific “weakness” is needed to make those decisions.
