🔓 How to Unlock Soul Harvester

Defeat the stage boss to trigger the Final Swarm (an endless, tougher wave). Survive for 6 minutes to unlock Soul Harvester permanently. This challenge can be completed on any stage once the Final Swarm starts.

Checklist

Trigger Final Swarm after a stage boss.
Stack sustain (lifesteal/regen) and AoE clear.
Aim to keep mob density manageable while kiting.

🧠 How It Works & Practical Synergies

Each enemy kill spawns two homing souls that fly to other targets. This turns normal clears into chain reactions and is especially strong in high-density maps.

Weapons that accelerate kills

Aura

Constant proximity damage feeds steady kill chains in crowded waves.

Firestaff

Burn fields soften packs so souls can finish stragglers.

Revolver

High single-target bursts create frequent overkills that spawn souls immediately.

Advanced mechanics (Unconfirmed)

Community testing suggests soul damage starts at 5 and increases by about 1.75 per player level, and appears to scale with the player’s Damage stat. These figures are not yet validated by official patch notes and may change in updates.
