Draconic Lucabration

Motes of invisible arcane power split and restitch at your whim. A creature you touch regains 2 spell slots up to 2nd level. Once you cast this spell, you can’t cast it again for 24 hours.

At Higher Level. If you cast this spell using a spell slot higher than 3rd, the target regains 2 spell slots of a level one higher than 2nd for each slot you use higher than 3rd.
