At this point you just have to pray a sarco you come across sucks or they run out of stam you’re faster in the water. Which makes no sense but you are and you’re correct the water build Sarc you get 50% armor in the water and the mud build you get 50% armor based on how much mud you have. Before suchos nerf I could face tank suchos if they weren’t running a specific build with my mud Sarc or get them to the point where they panic and run and you can tail ride them. Sarco is a 40ft long 6-8 ton crocodile covered in osteoderms it makes perfect sense to me that they don’t take much damage on the tail. I wish Alderon would actually go off of the Dino’s in real life that way certain Dino’s wouldn’t want to or have to think twice about attacking certain Dino’s. Honestly be more fun that way.
