I've got 18 in total. Technically 20, but I sold one and gifted the other away. I had plans to sell them, but now I'm not so sure. I'm enjoying the game so I think I'll keep them around.
2! both of them are permas :D they're also the only Wildies I've recruited so far… I've encountered three today and all of them got insulted and ran off when I barked at them.
i think i got 16 in total - i sold one for some quick moonstones though and gifted another. i traded some around but ultimately still have 14 in my den right now. i can't decide how many i want to keep though, 14 would be a lot of projects!
