Bring a lot of Narcotics! I used around 200 Narcotics on a level 140 on official (I used an elixer which boosted the tame to 30% so I recommend that you take at least 300 Narcotics). I also tried both cooked prime meat and cooked meat and it seems they like the cooked meat the most.

Trapped mine in a all rounder trap with 15 foundation’s, doorframes all around (3 high) and stairs on both ends or the trap.

Hope this helps.
