To knock out a lvl 150,you need 17 boulders +/-. The maths are simple: boulder give 400 torpor to karkinos each good shot.
(torpor to lvl)/400 = number of boulder (round up)
Like so dododex will know now.
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!!!
