Ok so I've been through taming this thing. I made a trap with 3x3 high door frames and 4 ramps at the place it's coming from. I made a wooden trap but it lasted, even though it was like lvl 120 or smth. So it took me like, 100 tranqs to knock it out. So when it knocked out all i fed it was Mejoberries and narcotics as Bio Toxin. When it tamed it was like a killer. It even killed a skeleton alpha rex! So me and my argy went to ice place and while i was getting materials some random yuty and carnos attacked me. So i died. But i went on my therry and destroyed anything in my way. Though my stuff was on a hill sode in ice place. So i got it, and my argy and i rid my argy and told the therry to follow. Then i went back home and on. Hope you get the right taming effectiveness! (Btw i did it in halloween and it tamed in 2 dodorex moons/nights)
