Phase 1 – Pale Rider’s Arrival:

• Nytherion descends from a pillar of swirling frost, wielding Scythe of Eternal Sleep.
• First attack: sweeping melee scythe strikes and spectral charges.
• Adds: Deathspawn Shadows periodically rise from frozen ground. Player must balance attacking Nytherion and managing adds.

Phase 2 – Necrotic Wave:

• Nytherion channels death energy into the ground, sending rippling necrotic waves across the battlefield.
• Player must jump and dodge to avoid damage while using environment (frozen pillars, necrotic tombstones) as cover.
• Weak points: glowing frost cores along scythe and horse armor—hitting them staggers him.

Phase 3 – Summon of the Fallen:

• Nytherion calls forth spectral riders of fallen generals, charging in coordinated patterns.
• Player must use platforming and movement to avoid collisions and simultaneously target Nytherion’s weak points.
• Environmental hazard: icy spires periodically collapse under attack or spell effects.

Phase 4 – Death Unleashed:

• Nytherion envelops himself in a shroud of pure necrotic frost, increasing attack speed and damage.
• Player can topple frozen spires onto him to break the shield momentarily, opening windows for heavy damage.
• Ends with cinematic: Nytherion is finally defeated, riding into the frost as his essence dissipates into the ice.
