The final boss in MegaBonk stands as one of the game’s most punishing challenges. Surviving until Phase 3 feels triumphant—until the battle shifts ruthlessly. Your carefully curated build becomes irrelevant: the boss strips all weapons except your starter, forcing a narrow, grinding duel.

Boss Mechanics Breakdown

• Weapon Removal: All weapons vanish except your primary. Late-game builds crumble instantly, especially those relying on lifesteal or multi-weapon synergies.
• Massive Health Pool: Estimates suggest 8+ million HP, compounded by invulnerability phases that require disabling arena beacons. Failing to deactivate them quickly triggers a full heal.
• Deadly Attacks: Evading is mandatory. Red AoE explosions, homing orbs, and knockback effects dominate the arena, making survivability nearly impossible for slow characters.

Optimal Strategy Guide

• Primary Weapon Focus: Fully invest in Bone, Revolver, or Axe early. Avoid spreading upgrades across multiple weapons.
• Critical Upgrades: Prioritize attack speed to pressure the boss during beacon phases. Stack damage boosts, projectile count, and shield regeneration tomes. Avoid silver gain or projectile speed upgrades—they’re useless here.
• Survival Tips: Movement speed and shields are key. Health/lifesteal builds falter due to limited weapon access. Use characters with strong defensive abilities or shield-focused upgrades.

Success hinges on anticipating this fight early. Build your entire run around maximizing your starter weapon’s potential—creativity takes a backseat to brute-force optimization.
