Sköll boots

Sköll boots are boots received from killing Sköll in the 2012 and 2013 Winter events. They double Woodcutting and Agility experience when worn. The boots start off with 100% charge. As players gain experience in Woodcutting or Agility, the charges decrease. The rate the charges are used up depends on how much experience is gained and on the level in the skill the player is training. Having higher skill levels allows more experience to be earned per charge.

If lost, the boots retain what charge they had before, and can be retrieved from Diango or the Fremennik citizen at the gate while the event is ongoing.

Sköll boots lost their charge on the 16th of May 2013. The Sköll boots can be stored in a Toy box in a Player-owned house.

If the charge from previous Sköll events had not been used up prior to the event, the boots retain their charge and can be recharged fully after the previous charge has been used up.

On 13 November 2013, Jagex made a change and stated "Hati paws and Sköll boots now give the correct amount of bonus XP." This resulted in the bonus XP remaining from the prior event being reduced to 10% (e.g. starting at 500K XP, 250K remaining in May, 25K claimable as of November).

Trivia

 * Contrary to popular belief, time is not a factor for using the charges. This confusion originates from when the Hati paws were first announced. It was said they would last for 10 hours of combat, but this was changed when the paws were released.
 * Even when the sacred clay hatchet is in inventory and when the player is not gaining bonus experience from it, the Sköll boots do NOT give you any bonus experience when wearing them.
