I've tested the creature out for a couple of minutes and here's what needs improving. Model itself is warped in abdomen, shoulders, and back. Not all details from mod image appears in-game. Walking on slight inclines and or rocks or terrain causes the Kaitan to stutter frequently and teleport whilst riding, Oxygen stat is too high and causes the Kaitan to practically sprint in water. Things that should be added: More Abilities maybe like a fire breath or more punches just so it feels worth attempting to tame, Should have a specific spawn region like Giga and due to it's size and power only one should appear in the world at a time, I have yet to see a saddle for this I don't know if it's implemented or not but if not then a saddle.
Do remember I only tested this for 10 minutes tops and am still testing but I only used this mod whilst testing so no conflictions to my knowledge. I'll keep this on my watch list and wait till it's patched more to use but still very cool and continue improving it Prome. I'll definitely use this once it's worked on some more, also one more thing, please update the mod page description with more details about this just in case I missed valuable info. So far I can't wait for more updates, keep up the great work!
