Yeah, I haven't put money into either of them, no point really. Just ends up taking longer to get what you want if you don't put money in.
I made it back up to 30 stones because of log-in rewards and ares realm so I tried for Ludger with the 10 rolls for 30 stones but no luck. The one after that is 10 rolls for 50 stones with 1 guaranteed featured summon but I'm all out. Probably should have saved em but oh well
