Utility Tips

What is a rex used for? rex battling strategies in ARK: Survival Ascended & Evolved.
This is basically the go to choice for almost all the bosses.why? because its the one of the best for fighting bosses especially forest,ice and megapithecus, because point you probably don't have a giga at that point,it has high HP and high damage and if you breed it up..it's gonna crush the weaker bosses.if you want to add up the damage output of the Rex with the yuty then sure you can do it if you're willing to go into the snow and possibly get ambushed by purlovias.
If you are going to go hunting with it, it’s best to just wait until you are on the right level and get enough materials to make a saddle and ride it. If you can’t wait till then, definitely don’t hunt near water or the ocean at least. On my first day of my first Rex, I got carried away, got on my Carno, and started to attack a Brontosaurus. It retreated into the ocean and my Rex chased after it, then a surprisingly big swarm of Megs attacked my Rex and I couldn’t save without getting out alive. It managed to kill a few Megs, but it wasn’t a match for all of them. My point is, if you want your Rex to live, think before you are about to do something with it.
