Aura of Power

You channel your power to its limit and your eyes begin to glow brighter and an aura the same color as your eyes appears around you. You may add 1d4 (changes at higher levels) to your spells and attacks as extra damage. Your walking speed increases by 10 feet. Roll whatever die you use as damage and subtract the roll from your armor class. Your armor class will reset to normal when this spell is deactivated. You can deactivate this spell without using an action during your turn, but you cannot deactivate the spell in the same turn you activated it.
