I have seen numerous players talk about their 'projects' for different tagged sylesti. What is a project? and how would you go about starting one?

themmed project are often final outcome that a player want to get with the perticular themme. Usualy it end with a 6 vis offspring with the wanted traits and mutation (or just as a rendom traits 6 vis). The importent for the project is to keep the themme pure so no crossbreed, rendom pets that don't have the themme or generated pet can be added to the gene pool, you nead to work with the traits that you can have.

Those guide should help you :

PRojects typically refer to breeding projects. You play around in three generator and come up with something (fixed colours and traits), that you want to create. For themed breeding projects, the colours have already been "fixed" by the theme, so you just decide the combination of traits you want.

Then, you start your projects, either by buying/breeding pets till you get the right combination of traits, of can gather essences to generate what you need to start breeding. In the case of themed projects, your starting must be pets that are of that theme, whether tagged or purebred.
