▪ Is there a line drawn where you don't like trading your lists for treasure/gems?
I haven’t traded any pets for gems but I have traded for several pets and paid in gems. I usually try to offer the full amount of their worth in gems or I give them the equivalent value in old apparel/items/familiars/skins and accents, or a mixture of both. It might take a while to find someone willing to trade but usually someone will after a while. I’ve traded for quite a few mainlist pets in exchange for pure gems, or a mixture, including my Tiger Dog, Sunjewel, Dogtag, UR Bee, UR Phoenix, and more, but I am an older FR player so I had a lot of expensive older items to trade as well. Sometimes people will trade for items that they can’t afford to buy with gems.
But I can see someone willing to trade their UR Lion for pure gems, especially someone who might be in need of a large amount, but it might take some time.
Don’t give up!
