just wait for events on official servers and tame it easier.

i used the 4 metal dino framegates and 2 big bear traps.

a wyvern with 25k hp and almost got killed cause i couldnt trap it fast and get many bites. think about this cause they lost the aggro with ease.

a rifle with 188% (aprentice and another mastercraft just in case)

it was lvl 95 on a 3x boost so i used 170 darts like less than 200 narcotics and 5 kibbles yellow ones.

the torpor goes down as hell make sure you cleaned the zone against any potential danger to you cause you need to stay close.

once on the trap is just shooting at it no more worries so preparation and timing is the key.
