Scorned Spellweave

You gain the following benefits.

Ability Score Increase. Increase one ability score of your choice by 1, to a maximum of 20.

Aberrant Magic. Magic swirls within you wildly, the weave itself beckoning you to wield it. Whenever you succeed a save check against a spell by a margin of 5 or more, you can use a reaction to recover a spell slot equivalent to the level of the spell you avoided or lower (1 level 2 spell slot = 2 level 1 spell slots). Additionally, when you critically hit with a cantrip, you may use a sorcery point to raise the damage die by one (3d6 becomes 4d6, etc).
