Veilbound Metamagic

Constitution 13 or veilweaver level 1, ability to cast 2nd-level spells, any metamagic feat.

When you gain this feat, choose one metamagic feat you know. Once made, this choice cannot be changed.

Once per day when you normally prepare spells or regain spell slots for the day, you can bind essence into this feat. Once essence is bound, it remains invested for 24 hours or until the next time you weave veils for the day.

For each point of essence invested in this feat, you may select one spell you know and can cast. When you prepare or cast a selected spell with your chosen metamagic feat applied, the level increase of that metamagic feat is reduced by 1 to a minimum of +1.

You gain 1 point of essence.
