Improved Arcane Core

You're arcane core embedded within you can now harness more power and channel it more potently. When you gain this feature, you gain the Arcane Recovery ability from the Wizard Class. Once per day when you finish a short rest, you can choose expended spell slots to recover. The spell slots can have a combined level that is equal to or less than half your level (rounded down), and none of the slots can be 6th level or higher. For example, if you’re a 4th-level spellcaster, you can recover up to two levels worth of spell slots. You can recover either a 2nd-level spell slot or two 1st-level spell slots.
