Utility Tips

What is a rex used for? rex battling strategies in ARK: Survival Ascended & Evolved.
In my opinion, by far the best creature for certain boss fights. Good for the brrodmother, however megatheriums are better. It destroys the megapithecus. The only island boss I would not recommend it strongly is the dragon. For the dragon you want to use therizinos due to the reduced fire damage and use of veggie cakes. It does well against the overseer too.
The Rex good at:
-Tank
-Prime meat Collector
-causing other low level dino to poop when roar (only heard, not seen it with my very eye yet)
-wipeing dino life
But Rex bad at:
-Small attack radius which mean other creature can hit it from the side or back without you hitting them
-have hard time trying to turn around
-Can swim but lose oxygen while doing it
That all i know for know
Because rexes are slow, you can keep up with it and knock it out when it fleeing so they are easy to tame
Easiest way to find them is in snow biome on the island map, i found alot of them there
For everyone who wants to survive and thrive in the carnivore or Red woods forest, you should absolutely tame a Rex. The best creature you can have for land based raids is a rex. I tamed one who was very low level and killed three alfa allausours and their minus with 880 health lol. I level up 10 times and I then immediately went hunt down some dangerous dinos and conquer all thr swamp area. It was a glorious day of grind. All worth it.
Rexes are very useful all around carnivores with great health and melee. Having a good Rex helps when gathering meat, other resources (hide, chitin, etc.), and great for hunting/defending. If you're on a pvp server Rexes are for raids on other tribes as well, On Scorched Earth DLC a good Rex that has been leveled properly can solo kill a death worm but if not a few decent ones together will do.
