EASIEST TAMING OFFICIAL PVE:

4 metal foundations and 8 metal walls (double door frame) and ramp into one side. Bit like the early game traps. Throw a ln extinguisher grenade at it to put the flames out every time it does its jump and flames come out of its nose. Then use a longness rifle and shocking tranq darts to KO it. Then place a medical stand next to it. With 50 narcotics and it will tame in less then 10 kibble in minutes. EASY. Ive tamed 8 in under an hour. Structures dont take damage and medical stand feeds the narco in keeping it knocked out.
