@Tiresias - I'd auction them off if I were you... dunno how much they're going for right now, but I managed to make 20K off only a couple yesterday, and I have 35-40 left.
I still have the original tree poison Palindrome, send me a message in game to discuss a trade for it; there are some cubi's I am looking for and maybe you have an extra. If not, I'm sure we can work something out.
