Best way to tame these (based off what I've seen and this crazy thing I call logic and experience)
1. Cryo a baby dino or two that has high drag weight as adult (bronto/rex/spino/etc) you might wanna check drag weight vs your max weight and empty your inventory completely (keep the cryo of course)
2. Make a saddle for a carchar and bring that too
3. Find carchar on a fast flier/high health flier with high stamina
4. Lead carchar somewhere near lots of easy to kill, preferably passive dinos but keep it from starting its rampage
5. When the carchar is no longer aggroed, go a small, but not too small distance away, put the saddle in your flier's inventory if necessary
6. Uncryo your sacrifice(s) and end them
7. Walk up to (should be passive) carchar while dragging a body, if it sniffs and roars into the sky, dash to your flier/away from your flier if you're willing to save it.
Alternatively, if it sniffs politely and curiously, drop the dead body, if you brought two babies, grab the other one while breathing heavily, the carchar might eat both so stay back a fair distance, repeat the process with this one if necessary
8. If the carchar likes the offering(s), the carchar will smile at you and offer you a ride, if not, step 7, then step 1 again
9. Get up on the glorious murder machine and go to the dinosaurs nearby, do a spin for them and compliment their scales
10. Then demolish all of the dinosaurs in a roaring, gruesome rampage while they all beg for forgiveness
11. Once tamed, the carchar's spikes will hurt your butt and you'll have to get off
12. Give your carchar a saddle, now you'll feel better
13. Continue step 9 until you get bored and head back to base
Crack crack crack… what was that? Well if looks could kill you would have died right there and then, This is the Carcharodontasaurus! Wanna tame one yourself? Where to find some? Or maybe how to defend yourself? All of those will be answered in one massive tip! So let’s jump in!
So where would you find one? They have the same spawn points as gigas, so if you want to find eithor of these apex predators that’s where you have the best chance of finding them. (Do note that they are a rare spawn)
How would you defend yourself? If you don’t have a flying tame next to you, then you can consider yourself very very dead. Other than that Carcharodontasaurus have a gnash defect they can inflict, very similar to that of a Giga.
Alright and that leaves us with how tame one, starting with all the supplies you will need: a tribe mate, a wyvern, 5-9 metal gateways, a simple bed and foundation, some large beartraps, and loads of patience. Start by finding one, fly a decent 150 meters away from it, (to avoid grabbing its attention while making the trap) and place the metal gateways in a circle, while leaving a opening. (Try not to make the circle to small because the Carcharodontasaurus HAS to move or the taming process will break) now that the cage is set, place the beartraps in the middle of the trap. The hard part is getting the Carcharodontasaurus into the trap. Use the wyvern to grab the Dino’s attention and lure it to the trap, and right when it enters and hits a trap, you run behind it and place the final gateways insuring the Dino stays in. Have your tribe mate watch the Carcharodontasaurus, while you grab the wyvern and grab large dinos, or vise versa, and bring them back to the enclosure, have your tribe mate kill it, while you grab more (keep doing this until you have a pile of dead things). So now your ready for the grueling taming process: have your tribemate drag dead animals to you, while you (hopefully having armor on) drag it and hold it near the Carcharodontasaurus, (the Carcharodontasaurus should sniff the air, and walk towards you, reach down and eat the corpse) after eating the corpse you gain a friendship meter, (this is a good thing) however you have to be quick, with haste continue dragging Dead Dino’s to the Carcharodontasaurus, and when the friendship meter is completely full, break down the side of the trap, and ride the Carcharodontasaurus. It is not tamed yet, but this is the last step and it’s the easiest: Go on the worlds bloodiest merciless dino massecre you possibly can. Eventually after eating and killing enough Dino’s the Carcharodontasaurus will have full taming effectiveness and then you have your very own Carcharodontasaurus! :D
After taming 3 carchars, this is what I have learned:
-the best way to trap these fellas is a 1x1 of metal dino gateways. You must have a bear trap in the middle of 3 gates to trap the carchar and then put up the 4th gate
-when trapped, the bastards will often refuse to eat, in order to fix this you can leave the corpse by it and simply go out of render from it. All tames must be out of render for this to work. If you left the corpse by it’s feet like I earlier said then by the time you come back the corpse will be eaten and the carchars progress will rise
-In the process of leaving and entering render to reset them, it a a must that you do this in a swiftly manner, as if you load in the carchar before you load the trap in the charcar has a large chance of meshing through your trap. I like to use a dino which can quickly elevate and dive for this
-when you have fed them enough corpses their progress bar will turn green and you can ride them, leave up the trap except for one gateway and start killing anything you see
-it is a good idea to head for highly populated areas instead of going for big kills
-elixirs do work on them so make sure you pop one when the car gets to 70% taming
-I’m not sure if this is possible with our rates yet, but if the car gets to a 99 kill streak it is very important that you roar. If you don’t and you hit a streak of 100 you will be kicked off of the car. Some dinos give a higher boost than just one, so if you feel as though you are getting to close to 100 you should roar sooner
-If you don’t get to 100% before the ten minutes is up it is much easier if you walk the car back into the old trap while you still have control of it. If you would like, you can also put up a new trap around the car while you still have control
-each time you have to feed and mount the car it’s timing effectiveness will tank. It will also fall if you take damage so make sure you don’t hit creatures with a thorn aspect like arthlos or kentros. It is also important that you negate all fall damage by jumping off of them because this drops their effectiveness as well
So friend and I tamed one this morning. Mated my rexes got 4 eggs to about 8% from hatching.(boosted hatch rates). Took the eggs close to where the carchar was, hatched one egg. Killed the rex and my buddy carried it up til it looked at him dropped the body and ran a little bit. Carchar ate the corpse and was ready to be mounted. No cage needed just got to have some massive balls.
