The person who said it’s only tamed for ten minutes is wrong they just didn’t understand the taming process you feed it creature bodies (gallimimus is favorite) then you can ride it but it’s not “your friend” you have to kill things with it wile you ride it then it’s tamed forever this person just didn’t do the last part of taming
Has a bloodrage buff that counts kills up to 100 and slowly decays when you don't make kills. At full rage, does x2.75 damage. Gets a 10 sec buff after every kill that greatly increases movement speed and gives stun immunity. Much tighter turn radius than a giga, runs faster, a little better stamina scaling. Seems like either bloodrage or the speed buff heals it a bit as well. Has a roar that zeros out the bloodrage counter. I'm told the roar gives a speed buff to allies. Tail spin attack a similar to a Reaper. Overall, it is comparable to or better than a giga in most respects.
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.
