Chapter Conditions

In Worlds 7+, one Chapter Condition is drawn per 100-wave chapter, at chapter position 50. Until the chapter ends it changes which enemies are more or less likely to spawn — the composition, never the enemies themselves.

The four cards

• Swarmfront — more light, fast swarm enemies
• Long Night — more heavy, defensive enemies
• Faultline — more mobile, ranged pressure
• Clear Memory — the base enemy mix, no modifier this stretch

The rules

• Cards only shift spawn WEIGHTS — enemy stats, spawn rate, rewards and abilities are never touched
• Exactly one card per chapter; reloading or resuming a run never rerolls it
• The Chapter-Boss wave (position 100) always fights clean — the card is cleared before it
• Refrain and Memory waves replace the composition entirely, overriding the card for that wave
