Frostmaw the Rime Matriarch
World bossRead its tale: The Rime Wyrm's Long Trail
Field notes
Mother of the rime wyrms, as long as a river. Its breath freezes waterfalls mid-fall; fire is the only thing it fears.
Where it lives
A lair on the far side of the Frostlands, on the hardest ground, away from the harbour. It rises when someone comes within 90 m, sinks back a minute after everyone has left, and returns a game day after it is calmed. It is as strong as the top of its land's level band.
How to calm it
Weak to (takes more): Fire +50%Energy +10%
Tough against (takes less): Ice −80%
Its attack: the claw sweep. It is slow to wind up (wind-up 1.1 s, then 1.9 s before the next).
Frostmaw the Rime Matriarch is weak to fire and energy but shrugs off ice. It's slow to wind up its claw sweep: stay behind them, and back away when the steam starts to hiss.
