Tainted essence is the currency used during the Cavern of Tainted Memories Treasure Hunter promotion. It can be gained inside the Cavern or found while skilling Divination. After 13 February 2018, essence was no longer obtainable via the portal.
When training Divination, three are obtained at a time in three-minute intervals.
They can be used with the currency pouch, and forged into rewards or converted into ten Divination experience each. If they're stored in the currency pouch, any further obtained essence is also stored in the pouch.
When converted into experience, a message is given: You convert your currency and receive - X Divination XP.
