When trying to KO the krab and if you do too much damage from hitting the legs accidentally like me lol..put honey on the last spot of your hot bar and toss it at him for fast health recovery, faster than dragging corpse to it.. use a ballista , took about 12 boulders for me to Ko a 145 ( approx as I missed a few)
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!!!
