If you only want to use one chain bola and your on a cluster server, tame a reaper, bola the tropeo and then use the reaper's right click attack. Adds 20 seconds to the bola each time you right click and it hits.
Normal bolas do work to immobilize them so you can build around and trap them, but you still HAVE to use the chain bolas to feed them, using normal ones will just say he doesn't wanna be tamed right now.
I found it very easy to use a snow owl if you have one. Let's say it's just floating up there in the sky and you can't seem to get it down. Use the freeze ability and it will force it to land, where then you can proceed to chain Bola it from a ground unit. It won't cause aggro to freeze it either so there's that. I did the same thing with a quets and it was relatively the same results, except the quets took back off again after about 3 seconds or so.
First trap it, u can find multiple online, then shoot it with whatever you like just hurt it enough so it won’t heal anytime soon. Then wait and it’s food will drop much quicker than just waiting with out hurting it. Then chain bola it and feed it the kibble once u have starved it enough.
On valq these things are everywhere nearby the castle and the area around it. I’ve seen them above trees and walking on the ground. They only attack u if u attack it first so use this to your advantage. Gl fellow tamers.
U can ride these without the saddle but u won’t get the jet boosts and missiles. They are also the biological version of a grinder. Use chain bolas on them and passive tame. Keep them bolaed bc they will kill u.
