In-game description
"This horn is tought to be made of one of the tusks of the great beast Kazgaroth. Who imbued it with its enchantment is unknown, but it is a very potent item. When blown upon, no sounds issues from the horn. Instead the user of the horn is incased in a globe of power for a short duration. The bubble gives the user partial magical resistance and a saving throw bonus, as well as partially deflecting incoming missiles attacks. The effect only lasts 18 seconds, and the horn draws from the life force of the user everytime it is used."
