Mind Crystal, Quickened

WONDROUS ITEM RARE MAGICAL METAMAGIC Requires Attunement

When a spellcaster is attuned to the Mind Crystal, once per Long Rest you can choose to cast a spell that normally uses your Action with a Bonus Action instead. You can only cast one leveled spell and one cantrip on the same turn.

You can use only a single mind crystal to modify the spell, and you can’t use a mind crystal and a Metamagic option on the same spell. Once you cast the spell roll a d20 and on a 1, it becomes a nonmagical gem worth 50 gp.
