Regen bracelet

The Bracelet of Regeneration is an onyx bracelet enchanted by the level 87 spell Enchant Level 6 Jewellery.

When worn, it doubles the natural rate of hitpoints heal, so one hitpoint is recharged every 30 seconds as opposed to every one minute. It is regarded by many players as a waste of an onyx, when instead it could be used to make the infamous Amulet of fury.
