Sir Lancelot is the strongest of King Arthur's knights. Players must help him break out of jail during the quest King's Ransom.
Players can also challenge Sir Lancelot during the Knight Waves Training Grounds activity, being the eighth and final Knight of the Round Table to appear in the Training Grounds.
His attacks can hit a maximum of 29 hitpoints and will temporarily lower the player's Defence, Magic, Ranged and Strength levels by 5 each. He is vulnerable to slash attacks and poisoned weapons.
