Armor Runes

Armor Runes (Su): You can attune armor to not interfere, with your spellcasting. When you prepare your spells for the day, you can also place armor runes on one suit of armor. Placing an armor rune on a suit of armor requires you to sacrifice one spell slot for every level of spell you can cast. You do not suffer the armor check penalty on your caster checks while wearing this armor for the day.
