The best way to tame these is to have a few (4-5) Wooden Billboards (Learned at Level 19, 7 E.P. total Wooden Sign prerequisite) and spam them around the Procoptodon when it stops to encase it in the Billboards. Best used with multiple people but still quite doable solo. This has been the most effective trap with such a low cost.
I come on here for tips about taming and ko and all i see is complaining about changes made. Can i get some actual tips on catching this thing, tried bear traps but couldnt get it armed in time to catch one.
