I was wondering if we could have more than 1 pair of Sköll boots or can we recharge it ?
You cannot get a second pair of Sköll boots. I tested that you cannot get two at the same time by participating in two Sköll kills. After the first kill I got a pair of boots and after the second kill I did not. Tip.it confirms that you can only get one pair and implies that they cannot be recharged.
