You will need to at least have a defence lvl 30, attack lvl 30, strength lvl 30, magic lvl 25, and prayer lvl 20. You will also need to wear full armor: full helm, plate body, plate legs, long sword, square shield, and any color cape (normal non-member cape). If you come to one of the PKings without those requirements, you will be kicked out. Oh yeah, I got a friend who got Zezima to join the Clan.
