The Hundred-Tailed Crown
A heap of rats. Every so often it bursts into a swarm: every rat you hit takes health off the crown. Then the rats run to a gold ring and the heap forms again.
Phases
Base health. The game multiplies boss health by 1.8, and by 1 plus 0.5 for every floor of depth, so the real number on its own floor is higher. 1550 × 1.8 = 2790.
Story
The rats of the crypt ate the tithe the Order buried with its dead. Gethrim counted every coin they swallowed and knotted their tails around the last one as a crown. Scatter them and they come back; a debt always gathers again.
Attacks
A cone, then a fan of five coins (seven later). In the last phase a second fan follows.
A short cone in front of it that knocks you back.
A lane through you, then the heap charges along it. Twice in a row in the last phase.
A red ring warns, then it bursts into rats. From the second phase half the rats rear with a red glint and bite.
Coins are lobbed onto marked circles. In the last phase the crown splits and a ring of rats circles the heap for good, flinging out when the outer ring blinks.
How to win
- Area weapons shine when it scatters: every rat you kill is health off the boss.
- Kill rats before they reach the gold ring. Each one that gets there heals the heap.
- In the last phase step back when the outer ring blinks: the rat ring flies out to it.
