Tankers Should bring tanking gear. This might vary depending on what boss you go to. For example: Bandos- bring your best melee gear and bring BGS. also bring Saradomin brews and super restore potions. Also bring a teleport in case your about to die during a boss fight. Zamorak and Armadyl should consist of the same thing except you bring the best dragon hide you can wear or Karil's. Attackers should maybe bring Sharks and Prayer Potions. Bring a teleport just in case too. Best weapons to bring if you are meleeing are either a Abyssal Whip or a Godsword. Please add more info if you think there should be more that I didnt cover yet :)
