Put 3 small metal Dino gates with a large bear trap in the middle of it. Incomplete square. Lead it inside with a fast argy or Ptera when it's trapped close it off IMMEDIATELY and shoot trans at it from a far distance because they have a ridiculous bite range. Have at least 10ish crossbows and more than 600 trans arrows and more than 1k narcotics cuz their torpo goes down too quick. I always tame high lvl gigas and give them to lower level newbies. That 1.5 boost makes there new lvl 215 so yea they pretty much have op gigas now.
I dare you to raise one!! They are savage if you got two high lvl parents (about lvl 140ish) and you get imprinting on it. The thing will become an adult with about 230% melee and basically one chomp any bronto!!! But on the down side you loose your job and your girlfriend
Make 4 metal dino gates and 1 large bear trap. Place three frames and door into an incomplete square and the large bear trap in the I between them. Lure the Giga into the trap and while its trapped place 4th down to make the square. Then just light it up with tranqs
