Consecrated Armor

You trace a holy symbol on your chest, and an invisible barrier protects you until the spell ends. Your base AC becomes 12 + your Dexterity modifier. If you are attacked by a Fiend or Undead, your AC becomes 15 + your Dexterity modifier against that attack. You can use your consecrated armor to determine your AC if the armor you wear would leave you with a lower AC. A shield’s benefits apply as normal while you use your consecrated armor.
