The bread and butter of the Rex is their high Health. A good way to find a high Hp Rex and know it's Hp stat before KO is to ride a mount and use the magnifying glass to see it's health. Griffins, Sabers, and direwolfves are all good mounts to ride while trying to use the magnifying glass on the Rex. Between 7000 and 10000 is what you want to aim for to make it worth taming.
So there are average rexes. They drop meat, prime meat, hide, and keratin. There are tek rexes. They drop scrap metal, oil, electronics, and element dust. There are alpha rexes. They drop tons of prime, cool loot, and some hide and keratin. So tell me: WHY ARE THERE NO ALPHA TEK REXES THAT DROP POLYMER??? thank you for your time happy hunting
This things are OP. In valguero, the only things that can kill it once it is tamed are gigas, rock golems and wyverns. But if you have a Rex and you don’t see any of these nearby, don’t worry at all. Pls up if you think this is true
