Ball is holding main quest item - so you won't miss it.
When you may expect to get this specific "kick Ball" quest?
After you saved the elven princess, talked to her, talked with Mark, talked with Dwarven King, talked with another dwarf in Mehgard - he will tell you that the something you need to find is probably in Demonis... If are you, dear reader, already so far - you know what I am talking about, if not, you will when you are so far.
Till then, Ball can't be beaten - he will (as designed) "banish" you...
Demons are nearly always to be bought when you perish / defeat Xeona (her castle is usually full of demon creatures) + there are at least 3 demon shrines which contain demon creatures as well - so getting demons should be quite positive / possible.
Of course - It could happen that if not lucky -> no demons
