Easy to tame but hard to knock it out. Took me about 447 tranq arrows. Always use soothing balm on them. Takes like about 3 hours to tame when no soothing balm used. Feed a lot of bio toxin first in order to make it really hungry. Also give it quetz kibble.
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
