This pristine mechanical gemstone comes in different colors, and provides a number of benefits when slotted into an artificer's helmet or armor:
Arcane Redoubt: The armor that this gem is slotted into is granted the benefits of the Enhanced Armor infusion, without counting against your infusion limit.
Recovery Matrix: At the start of your turn, you regenerate hp equal to the number of magic items you are attuned to, as long as you are not incapacitated.
Spell Capacitor: When you expend a spell slot of 4th level or higher to cast an artificer spell, you regain a spell slot equal to the level of the slot expended minus 3. So if you casted creation using a 5th level spell slot, you would regain a spell slot of 2nd level
