Using the cannon is better. Make a trap and get a markings in there to see where and how you can manipulate its direction,once u figured it out put the cannon at a safe place.build the trap a little higher makes it easier to aim.90-135 are a single cannon shot.
Tranq Arrows/Darts DO NOT WORK!!! To knock this out you need to use a catapult and shoot in only on it's back. If you shoot it on it's legs it will kill it. UP-VOTE SO EVERYONE KNOWS & TO GET DODODEX TO ADD THIS!!!
