The concept of this mod is great, and the so is the execution, at least on the surface, but it desperately needs to be balanced.
Like, some of the creatures feel fairly balanced and some just straight up aren't. The acro, deino, cryo and maybe the archelon feel balanced but the other three have some glaring issues. Firstly the xiphanctinus needs to have reduced spawn rates, and have a far smaller list of grabbable creatures. The sarco and barry, which will probably be most players' first transition into the water should not be grabbable. And even if you do get grabbed you should be able to get it off. The conca really only needs to not be able to use it's sand blast on larger creatures. If a conca can suffocate my titanosaur or giga with it's tiny sand cloud, that's just wrong. And finally the Brachi. Firstly it's stomp. Please just reduce it's base damage to somewhere around a thousand, and reduce the rate at which each level up increases it. And pleas make it so that it can't fear roar apex predators like Gigas, and wyverns two of the only surefire ways of killing it safely.
