Grand Exchange set containing Guthan's helm, platebody, chainskirt and warspear.
Guthan's set is Guthan the Infested's armour and weapon set. The set is obtained through the Grand Exchange, by giving Guthan's platebody, Guthan's chainskirt, Guthan's helm, and Guthan's warspear to a Grand Exchange clerk for the set. Completing the Barrows activity does not guarantee players will get a Barrows item. Like all Barrows armour, Guthan's armour requires level 70 Defence to wear. Guthan's warspear requires level 70 Attack to wield. Note that over a period of time like all Barrows items, the Armour will degrade, making it untradeable when (100) and below. It is only tradeable when fully repaired or fully degraded.
Despite Guthan's having more than average combat stats, it is mostly used by players to heal (and saves space that would have been used bringing food) and then they revert back to their regular melee armour. This method saves money and ultimately puts off having to repair the armour as regularly, this has proven to be a very good method of healing when out of food.
