Chapter Bosses
Every 100th wave in W7+ brings a far tougher Chapter Boss — non-blocking: the wave rolls on while you fight it.
Every 100th wave in Worlds 7+ spawns a CHAPTER BOSS — a much bigger version of that world's boss with the same abilities and tells. It never stops the run: waves keep advancing, enemies keep spawning, Conditions and Corruption keep working, and the boss simply fights among them until it falls. A persistent HP bar under the HUD tracks it while it lives.
The fight
- A Chapter Boss has several times the HP of that wave's regular boss and hits noticeably harder — from World 8 on, far harder still
- It is non-blocking: wave progression, spawning, Chapter Conditions and Corruption all continue while it lives
- It can fight alongside a still-living regular boss; both must be dealt with
- It can outlive its own wave — the HP bar keeps the fight readable while later waves roll in
Progression
Chapter Bosses gate nothing on their own: World 8 unlocks by reaching wave 300 in World 7, and start-wave boosts work off your best wave like everywhere else. The chapter beat is a fight, not a wall.
You never have to kill a Chapter Boss to keep progressing — the run moves on regardless. If it outguns you, bank the run, upgrade and come back stronger.
