A can of grease can be applied to grease any item. This protects them from rust and corrosion and also from grabbing attacks. A mind flayer can not attach its tentacles to a greased helmet, either. A greased item may slip when attempting to throw it, resulting in the object falling to the ground or sending it flying towards a random direction. If a greased piece of armor is cursed, there is only a 2/3 chance that it will protect you from grabbing or mind-sucking attacks.
