They are easy to tame at the Ragnarok highlands. As they can farm large amount of berries, can craft narcos in their inventory, can shot while riding it and have a strong topor-attack they are great taming assists. A saddled one with 2k+ hp, 2500+ sta and 500%+ dmg unskilled/born stats can easy knock out high rexes and other stuff. If the target run away you can easy follow and shot more tranqs. They have a high hp-regen and with full imprint they can get 314% speed. That is like a wyver fly and enough to run away even from alpha rex. If you cant tame a wild, maybe another player tried and failed. You need to knock it out to reset a failed taming.
