I did a mistake i did ascended but i forgot to use my ap points RIP so i have to wait for my next ascended tbh why can't you have a leave button for the portal
To get spells it is at the bottom right had corner that says "skills" click on it and get spells you will need skill points(by leveling your character up)
I will be introducing a back button in the next update (it was a problem with the way I coded the game, but I have since figured it out)
