Created by the Goblin Mage Nob-Nob in a foul ritual - which he concocted after sneaking into the Templars of the Arcane tower briefly, having to leave in the middle of the ritual due to unforseen interruption by a nasty golem ... the remainder of the ritual he 'figured out'. The resulting 'Belt of Invulnerability' had to be renamed due to some unforseen limitations on it's binding nature... that and the energies leaking from it constantly kind of look cool. Only the very bravest and most fearful of the Elite kamakazi goblins now get to wear such magnificent items! Brave adventurers typically return them after a time ... very nice of them.
