Should be s/b 15b a/w 17b for what I’ve seen, never purchased or traded such a craven myself so I would wait for any more responses and ask around (in game) some well known night lords if I were you. That being said, this is my pricing after checking the forums. The way I searched this up is by 91/12 = ~90/17 and found this reference: https://royals.ms/forum/threads/s-17-90-red-craven-rc.214303/ Good luck bud
Thank you for correcting me. I guees an s/b of 18b would make sense for us both. there you go @BeBo50
