You can actually tame him without traps or anything all you have to do is sneak up with your food of choice (1 baby rex, 1 baby spino, or 3 baby theriz) and feed him it. It works better with two people and i suggest letting him have a distraction to destroy such as a big gate.

And then for the second part just bring rare flowers and its just that easy!

Guide: Find High Level Carcha (150 or higher) (Any level if you want) Get your Rexes and Breed them (If you don't have rexes tame a Male and female to breed) Breed them and get any gender Baby Rex and Cryopod it (If you want to) Find the Carcha again and Trap it in metal gates Feed it the Baby Rex when it does a sniffing animation, It will have a green circle bar above it's head and you can ride it (DISCLAIMER: Get rid of the metal gates first then ride it) Ride it and then kill many, MANY Dinosaurs until it is tamed (ANOTHER DISCLAIMER: There is a taming bar below when you ride it) and that is the Guide to The Carcha Taming! Thank you and Good Day to you!

Make trap with 4-5 metall gates and a behemoth gate. Trap him inside . (Gate closed of course)Make the Same trap on the other side of the gate . Feed him with some Baby rex -spino -Wyvern. If he is in friendship Mode throw a Kryo with Bronto - gigas or other Fully grown Tames you can spare. When the are in Kryosleep on the other Side of the Gate .Release the tamed Dinos. Ride the Carcho open the gate eat sleeping Dino. Close the gate and get of him and throw another kryod Dino on the empty Side. Repeat untill you get 100% . That way you can get 100% taming efficency

Do NOT trap this dino. It will usually (not always but usually) aggro to the trap and when it stops it will nerf out and won't eat. It will sniff but not eat.

Get a very durable wyvern with lots of health, set it to follow you, let it munch on the wyv, throw out a baby rex, kill it and drag to carchar. Once carchar sniffs and eats you should be able to ride instantly. Repeat till tamed

For the first taming stage, it is based on drag weight. A baby Rex is good for getting 100% trust. Keep more than one dead baby Rex on hand. If it’s trapped, sometimes it will bug out and it won’t get the friend bar after eating it. Either try again if you have enough baby Rexes to spare, or leave render, come back, and try again.

The second taming stage is based off max health of the Dino you kill. It doesn’t matter how much health that Dino has lost, just what the max health is. Baby brontos work very well for this because they have a high max health at high levels, have low health when hatched, and don’t fight back.

The first thing is to find your carchar. I play on 5x taming at level 9 (max Dino level being 270), that roughly equates to 3x taming at level 5. Do be aware that anything less than 5x taming speed will kick you off when you reach a certain percent of taming. At 1x it’s 20%, 2x 40%, 3x 60%, and 4x 80%. This scales with taming level, not difficulty level. If you’re playing on anything less than 5x, have someone else there with you because you will need to bring it back to the trap and re-trap it before being kicked off at whatever percent and whatever taming. To put it like this: if you are on 1x settings, bring it back to the trap before reaching 20% and continue to chomp on things while in the trap until you are kicked off. You’ll need to feed it another Rex to make it friendly again. If you get kicked off due to running out of time, you will lose a large chunk of taming effectiveness. If you get kicked off because of blood rage or percentage, you will lose very little taming effectiveness. If you fat finger and dismount you’ll lose a good chunk of taming effectiveness.

Once you have your carchar and you know your settings, breed together Rexes for babies, and ideally some at or near max level brontos. Next, using either a dimetredon, otter, ac units, or the egg incubator, incubate the eggs until they have about a minute left on the timer. Pick them up/remove them. If you don’t remove it from the egg incubator in time just pick up the structure and they will drop in a bag. Put all your Rex eggs and bronto eggs on a flying Dino with a high weight stat (argys and dreadmares are good for this, if you want you can put it on a different Dino and black hole that Dino if you have a dreadmare and don’t want to worry about weight)

At your trapped carchar, build some two by two foundation squares with decent spacing. Place railing on three sides. I usually build anywhere from 5-10 of these, depending on the level of the carchar. Using an ac unit (you’ll need a generator with gasoline to run it), otter, or dimetredon, throw out 5-6 bronto eggs into each pen and hatch them all the way. Do this before you do your Rex eggs. When all your baby brontos are out, hatch your Rexes and claim the one you are going to shoot. It stops the rest of the babies from fleeing. Bring your bay over to the carchar and feed it. Pick up one of the gate traps and immediately hop on, don’t let it attack any of the babies yet. If it does, it will raise the blood rage but not the taming meter. You’ll have to wait for it to go back down. Go to the first pen and eat the baby brontos there. Keep an eye on your rage and taming meter, and how much the babies in that pen raised it. That will give you a rough estimate on how many you can eat before you have to wait for it to go down again, like if six babies brought your taming to 15% and your rage to 26, you can chomp on 12 more babies before having to wait to chomp again and bring your taming to 30% (if you’re on 1x rates you need to go back to the trap). If you’re on anything below 5x, bring the carchar back to the trap and have someone bring things to you to chomp on. Ideally you want to be kicked off due to percent or blood rage. Wear good armor for the tame so that if it decides to nibble at you, you don’t get one tapped.

The Absolute Best Method my tribe has found with taming these guys is to use a standard metal Dino gate trap for a giga, once trapped things get simpler.

The next step is to use baby Rexs, chuck one out near by but not to close, kill it then drag it close to the trap and when you see him sniff the air drop the body and move away to avoid taking damage.

One Rex baby is enough to fill his trust and you will be able to ride him, so you can demo a gate and use an elixir before you mount if you have them handy for that sweet bonus 30% taming.

So now the fun part, mount up and eat everything you see BUT you need to avoid Alpha Dino’s as you will not be able to kill them they take no damage from the Char as it’s still technically wild, be mindful to try avoid taking damage where possible as it will chip away at your taming effectiveness and on standard rates you will need to repeat the feeding of baby rexs a number of times through out the taming as it will kick you off and can try to kill you.

taming can be quite slow depending on how many wild Dino’s you can find in each run and you may need to repeat the process 4-5 times depending on level and current rates.

I found a 150 while flying around in a pteranodon. I ran out of stam

In a desperate attempt to save my ptera, I whistled follow and suicided. Then, I used my Argy to lead my pt away.

The problem: now there is a 150 carcha that walked down onto the western approach.

The big peoplem: my base is on the west approach.

The huge problem: I had passive rexes there

Relieving fact: they are baby rexes destined for being carch food
