If you think this Dino's torpor drops fast, wait till you try to tame a giga.

Bring over 500 narcotics or 250 bio toxins, you best use the exceptional kibble, starve it and drop the kibble in it's inventory for faster results.

To trap it, use a quetz

Make a big dino taming Penn, 1 behemoth 9 stone dino gates with doors.

And the most crucial, a F tone of patience and time to sit theree right next to it feeding it 10-20 narcotics/bio toxins every 5min or everytime you see the torpor drop.

You're welcome
