This boss really isn’t that hard. All you need for yourself is mastercraft or ascendant assault rifle (journeyman will do, but Isn’t as good). Then, to deal with his minions,get 4-5 high level troodons, because they will absolutely WRECK the minions. As tanks, Rexes are, of course, nessecary. And to keep yourself out of trouble, get a fast but durable mount, like an allo or a really high level raptor. Hope this helps!
