Brass Remnant

The Brass Remnant is the boss encountered in the Shattered Hour at the end of The Abyss Dungeon.

Attacks and phases

The Walking Hour ends at 70% health, the Dragon Break at 35%. The last phase and the two Echoes use faster versions of the three regular attacks. The Quickened Gears omen shortens those wind-ups by another 15%; Endings can also change their shapes and effects, as listed below.

Attack	Normal wind-up	Echo wind-up	Final-phase wind-up	Warning	Response
Brass Stomp	1.8 s	1.44 s	1.44 s	A 7 m-radius stomp, followed by a spreading ring out to 22 m.	Leave the inner circle and avoid the ring as it passes.
The Hour-Hand	1.6 s	1.28 s	1.28 s	A 34 m beam sweeping through 180° over 4 seconds.	Keep ahead of the sweep or move behind it.
Gear Volley	2 s	1.6 s	1.6 s	Circles of 3 m radius under up to five players.	Leave the targets and the burning brass they leave for 6 seconds.
Mantella Pulse	2.5 s	Unchanged	Unchanged	Hits everyone. Starts at 12% of maximum health, rising by 2 percentage points per pulse, up to 75%. Normally repeats every 30 seconds.	—
The Reset	8 s	Unchanged	Unchanged	Failure hits everyone for 70% of maximum health and heals the Remnant by 8%; success stuns it for 8 seconds.	Break every Heart before the warning ends.
The Hour Ends	2 s	Unchanged	Unchanged	At the fight deadline, repeatedly removes 99% of maximum health.	Finish the fight before the Hour ends.

During the Dragon Break, defeat both Echoes within 15 seconds of one another (10 seconds under the Dragon's Haste Ending). During the Reset, Hearts stop accepting hits in the last 0.5 seconds, so break them before that final moment.

See Endings and omens for modifiers and Rewards for the dungeon rewards.
