Opening

Reach the portal before the current opening

The Fire Force Dungeon opens every 15 minutes in the current Update 5.5 route. Finish training, equips, and boosts before the portal opens so the short entry window is used for joining rather than menu work.

Move to the portal before the opening.
Equip the strongest current team before joining.
Start long boosts only when they cover the wave run.

Wave route

Clear the current room before chasing the next target

Dungeon progress is wave based. Keep damage on the active room, avoid movement that pulls you away from the group, and use the end of each wave to check health, boosts, and the next spawn direction.

Stay with the active wave instead of splitting damage.
Save repositioning for the room transition.
If several waves load into one room, leave and rejoin a fresh opening.

Upgrade

Buy the upgrade that fixes the failed run

Dungeon has its own upgrade route, including an extra-time upgrade. After a run, name the blocker first: time, damage, or survival. Buy for that blocker, then retry the same route so the result is comparable.

Time ended first: compare the extra-time upgrade.
Damage stalled first: improve the active team before spreading resources.
Survival failed first: shorten risky movement and keep the group together.

Troubleshoot

Use the current fixes when entry or waves break

Update 5.5 includes fixes for portal entry, falling into the void, and multiple waves spawning in one room. If one returns, step away from the broken run, join a fresh server or opening, and retry after checking the portal state.

Portal does not accept entry: leave the prompt and try the next live opening.
Void or room state breaks: stop the run instead of spending more boosts.
Multiple waves overlap: reset in a fresh server before another attempt.
