Rimeback
The Company whaler Kestrel went north under Captain Aldous Vane and never came back. The pack ice swallowed her, and something lives in that ice now: Rimeback, a leviathan made of floe, with the Kestrel’s Hearthstove still burning in its chest.

Getting there
Section titled “Getting there”/warp Rimebacktakes you to Frostmere camp, beside the frozen Kestrel.- Climb down into the Kestrel’s hold. The ice gives way to Rimeback’s floe once you have reached Tidecaller’s Trials step 26.
- To get back, step into the return gate on the floe.
You can also use /bosszone after step 26.
Before you go
Section titled “Before you go”- Armor matters. Bites and sweeps are normal damage, so Protection works. Bring your best plate and enchanted golden apples.

The fight
Section titled “The fight”| Health | 7,500, plus 3,000 for each extra fighter (up to 18,000) |
| Arena | A frozen sea. Rimeback dives under the ice and breaches through it. |
| Enrage | After 8 minutes the whole floe starts freezing. Finish it. |
Phase 1: the floe
Section titled “Phase 1: the floe”Rimeback dives and surfaces through the ice. Watch for its bite, tail sweep, frost breath (bolts burst where they land) and ice shards. In a whiteout, listen for the ice cracking.
Phase 2: the floe cracks (66% health)
Section titled “Phase 2: the floe cracks (66% health)”- Holes open everywhere. Falling in is bad: the black water hurts more every second you stay in it (1, then 2, then 3 hearts a second, through armor). Climb out.
- Warmth. A Warmth meter appears on your action bar. It drains while you are away from a lit brazier and refills fast within about 6 blocks of one. At zero, the cold starts hurting you.
- Braziers get snuffed. Standing beside one relights it in a couple of seconds, and a snuffed brazier relights on its own after 30 seconds.
- The Kestrel’s frozen crew (Rimebound Sailors) climb out onto the ice. More join at each breach later on.
Phase 3: the Hearth (33% health)
Section titled “Phase 3: the Hearth (33% health)”The Hearthstove burns through Rimeback’s chest. After each breach, while the stove glows, strike the glow to stagger it. A staggered Rimeback takes a beating: hit it with everything.
