This will be a post of general information that everyone should know about powerstones. I would like to start collecting them as people are hitting level caps. Around the end of Feburary they are going to start adding raids which you need all the power stones and to Defeat the Kraken to be able to do them.
This one is not in english but has the location of all the turn in spots after you kill the boss of each island for powerstones. Will also help with the location of Fountains of Youth
