"A strange magical wooden shield of faeric origin. Held to your arm by vines that grow from its very wood, it feeds off your vital energies to slowly strengthen and withstand the attack of your enemies. "

You gain a permanent ability every 4 uses. You may earn the same ability multiple times. ''Note: The list of abilities may be incomplete. There probably also exists a cap on abilities earned.''
