Description: Tyrannosaurus was *one of* if not the most famous of dinosaurs. Its bite force is estimated to have been a few times more powerful than the bite of an American Alligator. While thought to have been to slow to catch its own prey, it has been discovered that the Tyrannosaurus had a muscle specialy connected from the tail to leg, allowing it to reach speeds of up to 30mph.
Just having a Rex in your base will encourage people not to mess with you on a pvp server. Regardless of level, Rex are a scary thing to see (and remember, people without telescope have no idea what level it is till they get closer than they want to be, so even a weak rex will scare off anyone yet who's yet to find crystal
The alpha. These things are strong. I was scared to do the mission to kill one of these, but I have a tip. If you find one near another carnivore ( say allosaurus, a pack of raptors ) lead the rex to them. Keep in mind they have a truce with spinos. The carnivores will attack it, bringing it to low health. Then, you attack. With everything. You don’t need the gun, you just need to kill the rex and the pursuit will end.
My personal favorite dinosaur and travel companion the rex is the best dinosaur for defense and hunting. It is like a ward for smaller predators and has an awesome roar that has a cool down period. They can carry a lot of weight and move very fast even when you're so heavy you can't run anymore. An astounding taming mount. Park one near a tame that's unconscious and most animals will stay away. Can carry alot of meat and prime meat for taming carnivorous animals. Gathers alot of trophies for offerings to the obelisk when you kill the right animals with it.
BOSS REX’s
For gamma bosses I recommend:
Hp 10K
Md 600
With 50 armor saddles.
For beta bosses I recommend:
Hp 15K
Md 1.2K
With 80 armor saddles.
For alpha bosses I recommend:
Hp 35K
Md 2K
With 120 armor saddles.
Buff your rexes with a yuty and optionally heal them with a pig. 100% imprint provides 30% more damage given and damage negation when the imprinted rider is riding.
I don’t recommend rexes for bosses that deal fire damage as carnivores take increased damage from it.
All of these estimations are assuming you are solo on official rates, the more people in the fight the lower the rex stats are required to be.
One of the best Dinos for base defense, meat runs and guarding your team in general. We have two in our tribe, within the first few hours our female laid 5 eggs. One is level 86 and the other 161, never have had to worry about them in battle, they've held their own against alphas, packs of the overrated Allos and many other Dinos that some may consider troublesome.
Best tame, once you get the ability to make a saddle, go an tame one be be prepared to be on the move constantly cause they cover a lot of ground.
Also avoid water combat unless you're in shallow water. I plan on taming a 3rd, They're the best in my opinion. If you can't tame a giga, the next best land carnivore is the Rex, hands down.
