Klank gives the player a free pair of his specialist gauntlets during the Underground Pass quest. If lost, the gauntlets must be re-bought for 5,000 coins if the player requires another pair. They are used to search the half-soulless' cages for a dove without being bitten. However, they are more popular for their combat bonuses.
Until the release of Recipe for Disaster, Klank's gauntlets were the strongest gloves in RuneScape.
A quick way to get to him is to teleport to the Death Altar and leave through a door outside the altar.
