Bosses
Standard runs clear a 6-boss route before the final portal. Endless starts after the standard clear and then continues into its separate boss sequence.
Boss Stages
Standard bosses are staged by map progress: each boss gate starts the next boss phase, and phase 6 is the normal-route clear point. Later phases use the same campaign rules with higher pressure, denser mechanics, and harsher recovery windows, so clearing a boss is both a checkpoint and a difficulty step.
Boss stages are not timed immunity phases. Fight the current boss, use the portal after it falls, then prepare for the next map's boss gate. After the final standard boss, the normal portal ends the run while the red Endless portal starts the Endless boss sequence.
Guard Breaks
Campaign bosses still take normal HP damage while guarded. Their segmented guard bar acts like a breakable shield: land boss-specific weakness chips, break all five segments, and the boss is stunned for a three-second burst window before the guard refills.
Each campaign guard has five chips. The correct chip action depends on the boss, such as fighting from range, stepping point-blank, killing a summoned objective, punishing a charge, pressuring through smoke, or hitting from inside a safe fire-ring pocket. A successful chip flashes the boss and briefly locks out more chips so the bar cannot be erased by one overlapping burst.
A full guard break pauses boss actions, boosts damage during the stun, and adds a lasting vulnerability stack for the rest of that boss fight. After the break window ends, the guard waits through its recovery before accepting more chips.
Guarded Bosses
Guarded bosses still take HP damage. Breaking the guard is a mastery shortcut: chip the five guard segments, stun the boss, then spend saved burst damage during the post-break stun.
If the battlefield shows Invulnerable, that is player-side hit protection being resolved, not a hidden boss immunity state. Boss state is shown through the guard bar, chip marker, stun visuals, and yellow recovery blink.

Endless Boundary
The normal clear rolls six distinct campaign bosses from an eight-boss pool. After the sixth boss clear, the final portal can end the run, or a red endless portal can continue into the Endless boss sequence one boss at a time.
