The Elven Shirt is a Clothing-class item, found in Mogall Forest. In order to find it you must explore a bit by checking every stump in each screen, as some screens have two apes that reveal paths, one of which usually leads to an item. The Elven Shirt increases base Defense by 22 and multiplies the Adept's current total Agility rating by 1.5. Its buy value is 1700 coins and its sell value is 1250 coins. Getting more defence from newer items in for example Kalay, or keeping more Agility at the cost of defense is just a matter of personal preference.
