Family gauntlets

Family gauntlets are a reward for completing the Family Crest quest. Players can take them to any of the three brothers from the quest and have them enchant the gauntlets with a special ability. Players can only have one effect at a time, and it will cost 25,000 coins to change the effect of the gauntlets.

If a player loses the gauntlets, Dimintheis will have found them and will give them back with its previous enchantment, making the original gloves unobtainable after they are enchanted once.

Cooking gauntlets
Bring the family gauntlets to Caleb in Gertrude's house west of Varrock. Cooking gauntlets greatly decrease the chance of burning fish, particularly lobsters, swordfish, monkfish and sharks..

Goldsmith gauntlets
Bring the family gauntlets to Avan at the Al-Kharid mine. Goldsmith gauntlets increase the Smithing experience of smelting gold from 22.5 to 56.2. This makes smelting gold bars more efficient, but will still make you lose a lot of money.

Chaos gauntlets
Bring the family gauntlets to Johnathon in the pub to the north-east of Varrock (near the Wilderness border). Chaos gauntlets increase the damage done by bolt spells.
