I have used all methods of trying to topor the megapithigus? spelling , and dodorex,Manticore, and others to tame, I was able to a few weeks ago, now, it will not do any torpor to them no matter what guns nor bows I use. The web states to use compound bow, but does not work, I used mod guns before, not will not work, dart guns, no. I have a Dodorex from a few weeks ago, I tamed with Primal fear bullets for torpor and was successfull, but not now, and with nothing. I also messed up and tried to upgrade the DodoRex saddle from 1500 to 7500, do not do that again, they cannot walk.
