Wondrous Item

Common

As a bonus action, a spellcaster holding the crystal can absorb the mana within the crystal, provided they have access to 1st-level spell slots.
The crystal replenishes one expended 1st-level spell slot.
If the caster is at their maximum spell slots, the regained slot exists as a temporary spell slot and lasts for 5 minutes before dissipating.

After being used, the Mana Crystal becomes an Empty Mana Crystal (small) , losing its glow and light coloration.
