Waymottin is a gnome found in the Ape Atoll Dungeon, near Zooknock. If you lose your 10th squad sigil during Monkey Madness, Sergeant Garkor will send you to him for a new one. Waymottin has no other role in Monkey Madness. He will be right in front of Zooknock trying to dig a tunnel in the wall with a spell. You can also use the drop method to obtain multiple sigils from him. The only reason he is pretty much there is to give you a replacement sigil. Earlier during the Monkey Madness, quest he would not talk to you until you became a member of the 10th squad.
