Don’t waste time trying to trap it with Dino gates. Build a pen and eat a rare flower and it will agro on you all the way to your pen. Use an owl so you can heal yourself because these things ice beam attack targets the rider. Owls heal their riders.
Pretty straightforward tame. Eats meat, so mutton's a great choice. Definitely want a trap with a ceiling. Only fits through behemoth gateways, or so is my experience. Mammal, so it has a gestation breeding timer and produces living offspring. Incredibly fast base speed, suggested to level Stamina for ultimate rocket power. Suggested stone trap.
I watched a video on this, thought I share. Watch nooblets for moré info. U can trap it with 2 small Dino gates. U place one, lead it into the doorway (so his head is stuck) then u can freeze it with an owl, get lose and place a second doorway a little bit past his head near his shoulders. Boom he can no longer move. (Hope this helps, if not watch his video😊 )
