When I first thought of getting one of these guys, I thought it would be a pain but it wasn’t. The biggest problem I ran into was I didn’t bring enough tranqs so I had to improvise and use a club and somehow got him knocked out (always bring more tranqs that you think you might need). Next, I decided to use a soothing balm which did the trick and I had a lvl 135 bronto (207 after taming) after only 15 min of waiting with mejos. Overall pretty easy tame but I would recommend that if by water, build a trap for the bronto so it doesn’t try to run to the water and drown itself.
These are the easiest tame ever, just get far away, shoot it with a crossbow repeatedly, when it gets close run and shoot, then boom u knocked out a brontosaurus (I literally have 5 of them that’s how easy they are to tame) please
