I was taming a lvl 20 the torpor drop is no joke. Bring at least 350 narcotics with and be prepared to wait if it's triple taming. Also if solo taming build a trap pen to pure it into with Windows. Make it out of stone they damage stone but it still takes them awhile.
Not sure if this will help anyone but if you built a platform and two walls up (I used thatch) and out a ladder so you can climb up then shoot it with tranc arrows and if you have enough it’ll eventually knock out but they wake up very fast so make sure to have enough narcotics,narcos, or bio
