There might be a bug in the newest version. Necklaces does upgrade with +0 to any stat. bevore update there were normal stats. Now upgrading them doesn't make sense.
I'm stuck in main story. King said to me to go talk with queen but she only greets me all the time :( Too much to play from beginning. Game is good but graphics in fight could be better.
