I'm gonna test this plugin right now :D looks like a great idea! As a suggestion maybe the posibility to make this powers with some configurable weakness. We suppose the Increase damage power is already set, the player get it but now he have mining fatigue or weakness near of emerald ore XD.
The possibility of turn on the powers with command or right click and only for an amount of time with cooldown to use it again would be cool too, I don't know, Im only very exited for this great idea of yours XD, I hope the next powers :D Thank You!
esta buen parece muy confiable el plugin tiene buen futuro eso me gusta espero que siga atualizandolo y que añada nuevas funciones ya que faltan muchas abilidades por añadir
