Why are ecsecens so expinve I want to to buy a lot of Griffin esscen to make a couple of breeding pairs with 6 vis each. but when I looked they where around 500,000 gold coins. I have found a Vulux esscen don't know what way I should us it. Will people post ideas for the vuluxe.

The answer to that question is simple : those essences are rare, you can get them by nurture pet, fighting, in satchel after a mission or you have to buy them with diamond. And griffin are a fabled specie so it's even rarer.

Those essence will allow you to actually create the designe of a 2 or 4 trait point (1 tp a for carry 2 for a visual) for depending so you can't just generate a 6 vis from it ( 12 tp ). The essence are usually used for projects (the 3 parents with different gene trick).
