The Cleansing Pool exchanges a random lunar item from your inventory for a Pearl or Irradiant Pearl. It costs no gold or lunar coins - the price is one of your lunar items, chosen at random. You cannot pick which lunar item is consumed. Ping the pool before activating to preview which pearl it offers in chat. Cleansing Pools are classified as shrines and do not spawn with Artifact of Command active or in Simulacrum.
+10% max HP per stack. Boss-tier item. Can be used as yellow scrap in Overgrown Printers.
+10% ALL stats per stack. One of the rarest items in the game. Cannot be obtained via Command or Recycler.
Ping the Cleansing Pool before interacting. The chat log will show whether it drops a Pearl or Irradiant Pearl. If it shows Irradiant Pearl, activate immediately. If it shows a regular Pearl, decide whether losing that lunar item is worth a +10% HP boost.
Cleansing Pools share spawn slots with standard chests, so they can appear anywhere a chest can on these stages. There is no guaranteed spawn - they are rare.
SotV DLC stages also have Cleansing Pools: Verdant Falls (Stage 1) and Aphelian Sanctuary (Stage 2).
With Artifact of Sacrifice active, no chests spawn - freeing up interactable slots for Cleansing Pools. Testing shows spawn rates roughly triple on Wetland Aspect and Scorched Acres and nearly double on Siren's Call. The best method for farming Irradiant Pearls.
You cannot choose which lunar item the pool takes. To control the outcome: carry only the lunar item you want to sacrifice before activating.
The Cleansing Pool exchanges a random lunar item from your inventory for a Pearl (80% chance, +10% max HP per stack) or an Irradiant Pearl (20% chance, +10% ALL stats per stack). You cannot choose which lunar item is taken - it is selected randomly. You can ping the pool before activating to see which pearl it will drop in chat.
Cleansing Pools can spawn on Wetland Aspect (Stage 2), Scorched Acres (Stage 3), Siren's Call (Stage 4), Verdant Falls (Stage 1, SotV DLC), and Aphelian Sanctuary (Stage 2, SotV DLC). They do not spawn in Simulacrum or when the Artifact of Command is active. They share spawn locations with standard chests, so they can appear anywhere those chests can.
No. The Cleansing Pool randomly selects which lunar item to consume from your inventory. If you want to ensure a specific item is taken, make sure it is the only lunar item in your inventory before activating. Lunar equipment counts as a lunar item and can also be consumed.
Irradiant Pearls have a 20% chance to drop from a Cleansing Pool instead of a regular Pearl. They cannot be obtained from Command Essences, Recyclers, or any other source. Each Cleansing Pool activation is an independent roll. To maximize Irradiant Pearl chances, use Artifact of Sacrifice on stages with Cleansing Pools to improve their spawn rates.
No. Cleansing Pools do not spawn when the Artifact of Command is active. This also means neither Pearls nor Irradiant Pearls can be obtained from Command Essence drops while Command is enabled.
Beads of Fealty is the best item to sacrifice since it has no combat downside - you lose nothing of value. Shaped Glass is the most important to sacrifice when it rolls since it halves your max HP. Always ping the pool first to preview which pearl drops, then decide whether the trade is worth it based on which lunar item you'd be losing.
