I was the same guy who encountered the level 260 male sarco at level 7 and said I'll tame it and guess what, I TAMED IT! basically i shot 2 tranq arrows at it on ascendant normal bow and then hit him with 10 clubs then used the soothing balm i got from Hunt: megapiranha pursuit and put fish meat and it took 9 fish meats. The dangerous part was i knocked it down near an lvl 100 alpha carno but thankfully both me and my sarco survived.
