i can nest you at some point to try and get mutations or just to play as

wix and seradae might be easy to get, taiyuelong a bit harder, sang will be cheaper but get more expensive later on since valentines day is past

for aeries, go onto the creatures of sonaria discord, often times they'll trade aeries spec for new creatures for showcases, mush, or large quantities of the same type of creature

i learned economics from survival game

there are giveaways once you are i think tier 1-2, join every single one you can, i barted for aeries, bought fluren spec (it was a new artifact creature, hard to get, and expensive) and traded it for aeries, and added a few other event creatures

i can look for it, it might be able to be seen if you go the cos's roblox page and hit discord

you find it?
