A mind shield is made after completing the Elemental Workshop II quest by smithing a primed mind bar into a mind shield while having the slashed book in the inventory; this gives 30 Smithing experience. Its defence bonus is higher than that of the elemental shield. When equipped, an orange circle emits from the centre, growing fast until the whole shield forms, looking like a wave rushing from the centre to the outside.
While tradeable, you can only equip the mind shield after you complete Elemental Workshop II.
A mind shield can be used as partial protection against the breath of skeletal wyverns and wyverns.
