Skarnax, the Storm Roc

Tier 10 · Dragonspine Peaks, Titanfall Ruins – catalog level 100, met at level 90. 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.
