Cleansing Pool

The Cleansing Pool is an interactable introduced in the Hidden Realms Update.

Functioning similarly to a 3D Printer, Cleansing Pools will exchange a random lunar item (including lunar equipment) held by the player for either a PearlPearl

Increases maximum health by 10% (+10% per stack). or an Irradiant PearlIrradiant Pearl
Increase ALL of your stats.
Increases ALL stats by 10% (+10% per stack).. The player must have at least one lunar item to activate the Cleansing Pool.

The Cleansing Pool has a 80% chance to drop a Pearl and a 20% chance to drop an Irradiant Pearl.

Notes

• Cleansing Pools will not spawn in Simulacrum or with the Artifact of Command active.

• Cleansing Pools can currently only spawn in five environments; Wetland Aspect, Aphelian Sanctuary, Scorched Acres, Sulfur Pools, and Siren's Call.
  • Based on extensive modded testing, with the tester going through over 300 of each stage, the chance for at least one Cleansing Pool to spawn is 9.66% on Wetland Aspect, 10.96% on Scorched Acres, and 15.33% on Siren's Call. The average spawn rates increase with the number of players.
    • Based on this, the chance for an Irradiant Pearl to be immediately available on these stages are 1.932% on Wetland Aspect, 2.192% on Scorched Acres, and 3.066% on Siren's Call.
  • Cleansing Pools appear to occur at higher rates than usual on Aphelian Sanctuary.^{verify}

• Based on further modded testing, the Artifact of Sacrifice greatly improves Cleansing Pool spawn rates, with the chances of at least one Cleansing Pool spawning roughly tripling on Wetland Aspect and Scorched Acres, and nearly doubling on Siren's Call. This is due to how the Directors populate maps with interactables; since there are no Chests to spawn, Cleansing Pools can spawn much more frequently.
  • Based on this, the chance for an Irradiant Pearl to be immediately available on these stages is increased to 5.796% on Wetland Aspect, 6.576% on Scorched Acres, and 6.132% on Siren's Call.

Tips

• Lunar items are characterized by their downsides, which means that gaining a large sum with the intent to convert them into pearls can prove to be dangerous. As Beads of FealtyBeads of Fealty
  Seems to do nothing... but... are functionally irrelevant outside of accessing A Moment, Whole, they serve as an excellent item to hold on to in the event that the player encounters a Cleansing Pool.
  • Players that aren't lacking in firepower can also hold onto a lunar equipment, even if they have no intention of using it.

• A good method of getting an Irradiant Pearl is to use the Artifact of Enigma and Artifact of Sacrifice. With Sacrifice enabled, the player can endlessly kill monsters and have equipment drop as a result. By repeatedly activating each equipment with Enigma enabled, the equipment will inevitably transform into a lunar equipment, which can then be used in the Cleansing Pool without spending any lunar coins.

  Items and equipment have a small chance to transform into a Lunar item instead.
  Items have a 5% (+5% per stack) chance to become a Lunar item instead. is another good method to get pearls with Artifact of Sacrifice since monsters will be able to drop lunar items.

• Avoid Cleansing Pools when playing as the HereticHereticThe Heretic is a powerful character who can only be accessed through extraordinary means.
  Class: Ranged
  HP: 440 (+132 per level)
  Damage: 18 (+3.6 per level)
  Armor: 0
  Umbra: Unorthodoxy Risen. Lunar items cannot be scrapped, and as such there is no way to guarantee that the Cleansing Pool will not remove one of her valuable Heresy items. (This is less of a concern if you have stacked multiples of those items.)

Bugs

• If the player activates a Cleansing Pool while playing as MUL-TMUL-TMUL-T is an aggressive survivor who has the tools necessary for any job!
  Class: Melee / Ranged
  HP: 200 (+60 per level)
  Damage: 11 (+2.2 per level)
  Armor: 12
  Umbra: Right Tool for the Wrong Job, and while holding 2 lunar equipment with RetoolRetool (Special)Passively hold TWO equipment at once. Activating 'Retool' switches the active Equipment and MUL-T's primary attack.
  Survivor: MUL-T, both lunar equipment will be consumed at once, but will only yield a single Pearl. Activating the Cleansing Pool while holding one lunar equipment and one regular equipment will only consume the lunar equipment, however.
