Purification: Idle Defense

Hold the line against hordes of shadow. Position your turrets, equip them with relics, and socket realm-altering decrees. Purify the realm, one stage at a time.

HOLD THE LINE AGAINST LEGIONS OF SHADOW

The sanctuary stands as the final bastion of light in a fractured world consumed by shadows. Forge an impenetrable defensive line of machinery, withstand hordes of monstrosities, and harness their souls.

Purification merges Tower Defense with the exponential growth of an Incremental Idler. Every stage rewards you with souls for talent upgrades and ancient relics that transform your wall into an ever-growing fortress.
