Ulfmar, the Rime Mammoth

Tier 6 · Rimehollow Caverns, Frostpeak Mountains, Hrimfell Vault – catalog level 60, met at level 50. A fight for three to five heroes; it returns 12–24 h after it falls. A hero 9 or more levels above it cannot hurt it. After 11 minutes of a fight it rages and hits four times as hard – and twice as hard again every minute after, up to 256 times. Its health is for four heroes and grows or shrinks 15% with every hero more or fewer fighting it (up to ten) – a hero counts once they have dealt 0.5% of the four heroes' health and stand no more than 8 levels below it. Regenerates 0.05% of its health every second while it lives. A stun interrupts a boss's cast, even while it is unyielding. Bosses take half of every stun, root and slow; a stun or a root makes a boss unyielding for 8 s, and until then it shrugs off further stuns, roots and slows. A slow never makes it unyielding.

Phases

at 66% and 33% health
  • 66% – Ulfmar trumpets at the peaks - frost wolves come howling down the snow! (3 × Frost Wolf, worth nothing, gone when the boss falls or resets)
  • 33% – The runestone on Ulfmar's back flares blue - ice trolls lumber out of the drifts! (3 × Ice Troll, worth nothing, gone when the boss falls or resets)

A new phase brings its own ability into the fight; the boss pauses a few seconds between two casts.
