Wondrous Item

Common

A gemstone which contains a crystallized bit of spellcasting magic. When you cast a spell that has a casting time of 1 action while holding a mind crystal, you can use it to modify the spell. You can only use a single mind crystal on a spell cast and you cannot use a mind crystal and metamagic on the same spell cast. Once a mind crystal has been used it becomes a nonmagical gem worth 50 gold.   This mind crystal enables you to cast a spell without any somatic or verbal components.

This mind crystal shimmers with a dull gray hue, similar to a shard of diamond.
