Lord Skwol was a hydra boss summoned at a Greater Windstone in Silithus. He was a powerful elemental being requiring 20-40 people to defeat. He was significantly more difficult than the other 3 summoned bosses. Summoning him required a full Twilight Trappings set, a Twilight Cultist Medallion of Station, and a Twilight Cultist Ring of Lordship.
