Rift Crystals
Collect Rift Crystals from Bitterblack Isle
Build a Rift Crystal reserve from Isle exploration for Bitterblack Isle services such as Olra’s purification.
Bitterblack Isle rooms and chests; return to Olra at the harbor to spend crystals on purification.
Repeat exploration and chest checks on routes you can manage. Enemy and chest contents vary. Purification is a separate spending step that turns a cursed relic into an item and costs RC.
Pause when you have the RC reserve needed for your next planned service, or switch to an easier opened route if the current rooms consume too many supplies.
Open a guide to find other locations and see what the item is used for.
