Sir Tristram is one of King Arthur's knights. Players must help him break out of jail in the King's Ransom quest.
Sir Tristram is the third of the Knights of the Round Table to appear in the Knight Waves Training Grounds activity. His attacks will temporarily lower the player's Strength, Ranged and Magic levels.
- During the King's Ransom quest, when locked in the prison cell, he is sitting on the ground and throwing some kind of hopping ball on the wall. This is reference to the 1962 film "The Great Escape", where Hilts is seen throwing a baseball against the floor and rebounding off the wall whilst locked in his prison cell.
- Sir Tristram is the only Knight of the Round Table that uses a full face helmet.
