Arcane Engrainment

Once you take this feat, you gain the ability to sacrifice all of your 2nd and 3rd level spell slots in order to make an object you have infused permanent. This ability MUST be used when you have all of the required spell slots unspent (for example, immediately after a long rest.) This ability becomes available again after 1d4 days per level of infusion made permanent. The item no longer counts against the number of infusions your character has and retains its magical properties if your character dies.
