Wondrous Item

Uncommon

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 reroll up to three damage dice for the damage dealt by the spell. You must use the new rolls if you choose to reroll any damage die.

This mind crystal glitters with a lush orange complexion, similar to a topaz.
