Paracer with a platform saddle, cannon on the back. Build a half circle of stone pillars, 2 high, to kite it back to. Make sure the Paracer has plenty of health as it will take some serious damage through the process. Bring soup that helps with health regeneration and feed it to the Paracer before the fight. Have the person firing the cannon balls put as many cannon balls in inventory as you can carry. Line up the shot prior to the kite. Quick KO and pretty easy tame.
