Arcane Life Burner (5e Feat)

Prerequisites: Pact Magic or Spellcasting class feature
Either by boon, blood, prayer or study magic burns in your soul.

You gain one metamagic option to apply to your spells.
As a bonus action, you can expend one hit die and gain sorcery points equal to the die roll. These sorcery points last until you expend them or finish a long rest. (These are in addition to the sorcery points gained from another source but can only be used on metamagic.)
