I think this event is very hard (energy!) and by comparing it to older ones Im not sure I will finish it, so Im gonna go for the knight first - 53 so far... it's taking really long with this stupid random drops. HOW can S8 make random drops when we need 80 tokens?!
Other question: IF we finish the event and get the halloween castle version will we be able to switch between normal and Halloween Castle version also after the event... or will the Halloween version disapear and we either have Halloween all year or loose this prize and change back to normal? O.o
