Arcane Skill

When you fail a D20 Test, you can expend a spell slot to gain a bonus to the roll, potentially causing it to succeed. The bonus equals 2 plus the level of the spell slot expended.

Vital Fuel

When you finish a Short Rest, you can expend a number of Hit Point Dice up to your Proficiency Bonus to recover expended spell slots. Choose spell slots to recover that have a combined level equal to no more than the number of Hit Point Dice expended. Once you use this feature, you can't do so again until you finish a Long Rest.
