To tame Pyromanes on official you will run into the same issue I did, lack of dinos. I suggest kiting it to another island and using a boat with a small building ontop to kite and shoot from while it’s in the water. Basic pump shotgun works very well for the first phase. Once you do enough damage it will be rideable for a few seconds move to it and climb on its back to start the 2nd phase. Run around and attack Dino’s and absorb the flames to take the pyromane. Absorbing the flames also heals the pyromane so don’t be worried about fighting rexs and the other carnivores. Having someone scout ahead is very helpful. Once you get it to 100% do the flame boost and you have yourself a very hot kitty 😁 have fun and be safe.
