Yeah, so far seems like event tokens are frontloaded, kinda opposite of the Halloween event. I guess I'll try to hoard up snowballs for experimenting with mass rerolls, maybe there's an Exodia hidden in some combination of items. Though doesn't seem like it's the case with what I've seen atm.
I don't quite understand what exactly you want to do, but keep in mind - tokens are reset at the beginning of the event. It is at the beginning - after the end that you can still buy something in the store with the remaining ones. But at the beginning of the event, his tokens and all his progress are reset to zero.
No. I just finished two more times. Once with a perfect set. You can't get further than 25-26 anyway. And this is about 115 tokens. To buy something decent, you need to spend topaz, otherwise there is no way. Look at them, they double the characteristics at once! Damn cheat :) I would also like to have a stock of topaz for twenty thousand to be able to prepare :) And so - you will have to do without delicious artifacts for * 1.15 something.
Sadness! :)
