How to battle the snow queen

I ran out of patience collecting ice swords to get into the ice castle and bought them for 30 diamonds. If I click upgrade, will I be automatically entered into a battle with the ice queen? If so, what weapons do I need?

If you click upgrade then you get the option to start a new battle or join an existing one, but you usually end up on your own unless you click join from an invitation on your wall! The weapons needed are the same as those to battle the crypt boss and vampire boss, it just takes more of them! My advice would be to get some friends together at the same time who can take part, or you might risk losing the diamonds you've spent on keys because you won't have enough weapons to finish the battle on your own. Hope this helps!

Thank you highland lass! That's exactly what happened to me with the other battles. I didn't have anyone to join and lost all my keys. I will be better prepared this time. BTW, which weapons are used in all these fights? I've only done the bunker one with the medicines.

The weapons for all these fights are the items in collections 129 (Night Avenger), 130 (Van Helsing's Arsenal), and 131 (Daywalker's Arsenal) so completely different to the ones used in the bunker battles. The Night Avenger ones inflict the most damage!

Thanks again! I'll be prepared!

The weapons for these collections are dropping regularly after the latest update.
