You don’t need to trap this to tame, it’s a solo tame. If you run up to it, it will go into turret mode then you need to walk circles around it and keep hitting with tranq until it eventually tries to walk away *in turret mode so really slow walking*
They can be found in the Fjordur Map on the shores in the Volcano biome, along with some X-Trikes and a few more stuff- help spread the word so people won’t waste there time like I did searching in forest biomes :! — Bob the Builder
About a couple weeks ago, I was so lucky I was fooled into thinking a Velonasaur disregarded a shooter when mounting an Allosaur. Just now, I thought about how a Stegosaurus protects it's rider from arrows, and then shot at the Velonasaur between the plates in Hardened mode. I got very little damage comparatively, and knocked it out in relative peace. Stegos are the key, my packmates.
