You can channel the power of Xoriat to enhance your spells, but this takes a terrible toll on your mind.
Prerequisite: Devotion to the Cult of the Dragon Below. (Eberron)
Benefit: When you apply a metamagic feat to a spontaneous spell, you may take Wisdom damage instead of increasing the level of the spell slot level of the spell. You take 1 point of Wisdom damage for each spell slot level. For example, using Silent Spell would cause you to take 1 point of Wisdom damage. You may only use this to offset the increased spell slot level of a single feat per casting, and you cannot cast a spell if the increased spell slot level would place it above your ability to cast - for example, a 6th-level sorcerer cannot cast a silent fireball through the use of this feat. Wisdom damage dealt by this feat can only be healed naturally at the rate of 1 per day. Magical healing has no effect. You cannot use this feat if the damage would lower your Wisdom below 1.
Special: If you abandon your faith in the Dragon Below, you lose the benefits of this feat.
