The ultimate final boss inhabiting the Vast Void — the most powerful enemy in the game. Combines all attack patterns to corner the player, then transitions into a high-speed, high-damage second phase at 50% HP. The core strategic choice is: burst through HP before phase transition, or outlast the assault with compound DoT through both phases.

Void Fang

A long-range lunge bite dealing massive single-hit damage. Speed and reach far exceed what other boss dive attacks prepare you for. The serpent coils into an S-curve before lunging — use that coiling motion as the dodge cue.

Dimension Rift

Spawns multiple spatial cracks across the field. Balls that touch a rift are annihilated — losing balls resets accumulated DoT stacks, making this attack extremely punishing. Rifts fade after a set duration; hold fire until they clear rather than risking your ball supply.

Poison Mist

Fills the entire field with toxic fog, dealing continuous damage. The mist also applies Poison stacks to your balls — if you're running a Poison build, this doubles as extra stacking time. When mist is active, increase attack tempo to close out the fight before attrition compounds.

Coil

The serpent encircles the field, restricting available movement space. Bounce builds lose firing angle options in the cramped arena; penetration balls and chain attacks perform better in confined spaces, effectively turning the restriction into an advantage.

Phase Transition (HP 50% or below)

At half HP, movement speed and attack power increase sharply. All actions accelerate, and Void Fang's reach extends further. Use Hourglass just before the transition triggers, or ensure heavy DoT stacks are applied beforehand to sustain kill pressure through the faster phase.

• Compound DoT (Bleed + Poison + Burn) simultaneously is the backbone of stable clears — continuous damage ticks even when hand-count drops
• Avoiding Dimension Rifts is top priority; losing balls kills your DoT momentum
• Use Hourglass near the 50% HP threshold to stall the phase transition opening aggression
• Coil actually improves penetration ball efficiency in the narrowed space — treat it as an opportunity
• During Poison Mist, push attack rate and aim for the finish before attrition accumulates on your side

Compound DoT Build (Stable — Recommended)

• Main Ball: Bleed + Poison compound
• Evolution Goal: Simultaneous Bleed / Poison / Burn multi-stack
• Passives: Pressure Valve, Hourglass
• Tactic: Stack multiple DoTs from the start; Hourglass at phase transition; ride continuous damage through the speed phase

Critical Burst Build (Shadow-oriented)

• Main Ball: High single-hit damage evolution
• Evolution Goal: Maximize critical rate and damage multiplier
• Passives: Silver Bullet, Pressure Valve
• Tactic: Crit-chain to 50% before the phase transition fires; win before Phase 2 begins
