You have a +2 bonus to AC while wearing this armor. Each of the runes can hold a (1) spell of that type: 1 spell of Lightning, 1 spell of Fire, 1 spell of Earth, and 1 spell of Water or Ice. These spells are stored within the armor until cast. There are 4 elemental slots on the armor, and you can cast each spell stored ONCE from the armor, until replenished by a spell caster casting a spell of that type into the armor, in a manner similar to that of a spell storing ring. 

This crude armor consists of thick furs and pelts.

Notes: Bonus: Armor Class, Druid, Combat, Warding
