Once you have a hero you can use a “Holy Water” to rearrange some of their stats. I believe it’s based on their level so if they are level 4 you can rearrange 4 points. If they are level 10, 10 points. Also the number of Holy Waters required is based on their level. I’m not sure of the exact breakdown but I think it’s every 5 levels it costs 1 extra holy water. Maybe someone can verify this and leave me a comment?
