I learned this from syntac: when you have it's trust bar filled, ride it then go on a killing spree with the carcha but when the dino your carcha is trying to kill is neutral or aggressive, it will attack the carcha as normal, but it will lower the taming sensitivity, so yeah don't get attacked too much.

You can drag a body and feed it to the carcha with your tamed Dino and it will gain trust in the exact same way as if you’re dragging it yourself. Just walk up to a corpse on your Dino, place your dino’s mouth over the corpse, and press G. This works with most but not all tamed dinos. Your Dino will move very slow while dragging a body though.

I’ve tamed a couple of carchas by carrying wild mammoth/yutyrannus to some safe area near a carcha on a Rhynio, killing them, pressing G, and slowly flying up to the carcha. Saved the life of several rex babies.

Step 1:tame two rexes(Doesn't have to be high lv)

Step 2:Let them do funky time

Step 3:Pet the baby rex

Step 4:have the best time with him

Step 5:Cryo him

Step 6:Sacrifice him to mighty charchar

Step 7:kill hundreds of innocent creatures while riding the charchar

Step8:You have charchar

Step9:remember that gigas will always be da best

Step10:your done

This creature might be slightly larger then a giga sense in the dossier it says Helena isn't even sure if it was fully grown and hopes it was. Meaning this thing at most is as tall as a giga or slightly taller. As for the abilities, it has a war cry similar to that of a yutyrannus but we aren't sure what it fully does, a tail sweep which is super powerful, a bite that even if it misses will cause critical levels of damage and the most noteable ability, the bloodlust ability. Just like a shark, it gets more vicious when it tastes blood and in the dossier it says it can take on larger creatures when it is in the bloodlust mode. Meaning the bloodlust mode is an overall attack boost to it. However there is one critical downside to this thing, when tamed it doesn't have a saddle so it may be like a wyvern to where you take all damage thrown at you and or like how shadowmanes are with their natural armor. We just gotta see what the Carchara is like on release.

Y'all don't actually need to trap it and prepare a baby Dino if U have a rhyniognatha, y'all just need to find a nearby rex or spino, carry it ALIVE to somewhere near the carcha but not near enough for it to notice U, kill the rex or spino U carried here and drag the body with ur rhyniognatha, it will be slow asf but trust the process. Once the carcha do a SNIFF animation just wait there for it to eat ur offering(btw if Ur wearing ghillie take it off just incase) and if it shows a green sign at top of it's head then congrats now just ride it and kill anything U see until it fully trust U(note that U might want a second flier or a parachute cuz rhynio won't follow U, maybe even a sleeping bag just incase ur didn't have time to react when it throws U off after tame)

Trap it, kill and drag a couple woolly rhino corpses to it. Do not drop the corpse, it will sniff then eat. You must make the kills. You can then ride it briefly and kill things to give taming progress. You can sacrifice tames for this. Doesn't seem to work with babies. Use caution, it's highly aggressive during the entire process and can hit you while you're feeding or dismount you while riding and attack you. As it makes kills, it gets a bloodrage buff that massively spikes damage output.

When I want to tame a carcha, I always use a baby rex because it always gives 100% trust, but i mostly find carchas in the cold biome on The Island, so its hard to incubate and hatch the eggs in the temperature of the biome, so I usually incubate it at home and get it at least 50% incubated, then use keys(usually 5)to hatch it, killing it and dragging it to the carcha.

The blood rage makes this beast’s uses fundamentally different from the giga’s.

The giga is roughly 2x carch. The giga has a rage that can be a contagious disease, making a huge army even deadlier.

The carch is faster, more stam, and has great healing. With 100 blood rage, this beast easily eclipses the giga’s damage. After a kill, they get healing and speed buff.

When in a large group, use giga’s since more carches = less blood rage per carch. But if only one tame is used and there are enough creatures for the carch to eat, the carcharodontosaur is without equal.
