Armor Rest

During a short rest or before a long rest, this spell can be cast to ignore the gaining  a level of Exhaustion during a long rest while still wearing armor, for the AC and enchantment bonuses. It can effect up to five people of a party or group that wear armor of medium and heavy armor. 

The verbal components, however loud, cool, silly, etc. are: "Woo! Full protection!:". In whatever languages the character knows.
