At first I thought it was offensive and inaccurate to say that these are stronger than rexes, but its not. I bred my 190 something spino with my 30 something, and it came out with more health than the dad. It also came with more damage than when I tamed the dad. These creatures with leveling are a whole different story. They are funner to ride than a giga or a rex, a giga looses stam after 5 second of running, a rex sometimes moves slow, but a spino with water buff can run nearly endlessly. They also are far better for traveling and safer. A rex gets triggers agroe of a few creature and so does the giga, but a spino can’t trigger agro even from a wild giga. I went into the snow biome everything got at least 3 shotted, same with the redwoods, and the swamp was easy, the mountains too easy. The only scary place was carno island cause I have never been there but I will get used to it. My spino Tidal Wave the dad killed 2 alpha raptors, nearly 3 but the other one despawned cuz my giga was above it when we were fighting it. No to mention the fact that spinos are essier to tame. I 100% recommend you tame a spino and breed it.
