Pure Blackstone Gem in Dungeons & Dragons 5e

Pure Blackstone Gem

Wondrous Item

Very Rare

A blackstone gem of impossible quality. Its stored magic allows users to cast spells of up to level 10 without expending a spell slot. After a certain number of uses, the gem will crumble to ash.

A brilliant black gemstone recovered from the depths of Pila. It is said that these crystals are formed when magical creatures die and then are compressed under the incredible heat and pressure of a tectonic subduction zone. Even holding the gem seems to fill one with magical energy.

Cost: 3,000,000 Midans
Weight: 1 lb.
