The Long Spine
A skull head with a trail of vertebrae and a barbed tail. The skull takes half damage, the glowing tail one and a half times. Vertebrae break off as it weakens.
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 × 2.7 = 4185.
Story
A coil shed from Ossivar's own spine, still hungry for names. It swims through the bone shelves as if they were water and surfaces under whoever still remembers one. Break it vertebra by vertebra; it grows no new ones.
Attacks
It rears, a lane is marked, then it lunges along it. Twice in the last phase.
A cone, then a fan of bone splinters. In the last phase a second fan fills the gaps of the first.
It burrows and travels under the floor towards you, shown by a moving mound and cracks. It erupts under a marked circle, twice in later phases.
From the second phase: the head circles you while bone spikes rise behind it, leaving one gap. Then the inside strikes. Leave through the gap.
Last phase: every few seconds half the vertebrae glow, then fire splinters straight out to the sides.
How to win
- Aim for the tail: it takes three times the damage of the skull.
- During a coil, find the gap early, before the ring closes.
- Do not stand beside the body in the last phase: the glowing vertebrae fire sideways.
