If you come across one with 120 wrestling, tactics, magic resist, and magery.... it could make a pretty nice pet. Personally, I’ve never seen a 4-slotter that nice. Doesn’t mean they don’t exist but when people want 20-30 million for a mediocre 4-slotter, I shutter to think of the cost of a really nice one. With the high skills in place, you could shore up resists, add MR, and add some HP. Unfortunately the one level up doesn’t give you a lot of wiggle room.
I’m waiting for the legacy dragons to become 100% stable and then I plan to build a nice one for each of my tamers. Those give you a lot to work with and should scratch my dragon itch!
