### Elemental Gem

*Wondrous item, uncommon*

This gem contains a mote of elemental energy. When you use an action to break the gem, an elemental is summoned as if you had cast the *conjure elemental* spell, and the gem's magic is lost. The type of gem determines the elemental summoned by the spell.
