Gem leopards (big leopards) are made of four colors of jewelry leopards, and what they need is leopards that have not become mounts. Riding cannot be used to synthesize gems and leopards.

As for the style of the mount, you can feel that you like it. Other people's ideas are in other people's eyes, and everyone's aesthetic vision will be different. Or you can get a macro of your favorite mount so that when you ride, you will click on one of these random mounts. As for macros, you can use Baidu (World of Warcraft random flying mount macro)
