i think there should be a monster hunt for every creature located at the start of the dungon entrance and you can do it as much as you want but the more you do it the less the reward..and have a small percent chance of some power points(im probley pestering admins about these but i dont have any money =p)
We're not going to change how the Power Points are earned (apart from gaining them from quests in the future) - I'm not sure what you mean with your idea however? You mean like find a particular creature and you will gain an xp/gold reward?
