Crystal Shard of Two Minds

Holding a crystal shard to your temple and imbue it with with your magics. The shard now allows you a range of spell options for an hour. You may either:

Have two concentration spells up at the same time. The first spell cast ends on a failed concentration check then subsequently the second on another failed check.

Up cast a spell to a higher level without having to use the upcasted spell slot. The lower level slot is used up however.

When a user casts a spell you can choose to absorb the spell, and must cast it on your next turn. If the spell cast is higher than you are capable of casting you can make a check using your spell ability modifier, the DC is 10 plus the spell level.
