I only have 2 99s so far. But heck did do 33 waves of Inferno. Kind of got bored with it. Will try again when I hit 99 ranged. Whenever that may be. More interested in melee.
Sorry but the Kourend Catacombs will never give me the same feel as Chaos Tunnels did when I ran through the maze to fight Bork the first time. RS3 will alway win with the Lore.
