I'm at 9.20, probably need to level up HP a bit (atm two hits and I'm dead):
However, I'm don't want to spend my boosters for a haloween task and I'm not able to skip this task - whenever I click on "Skip", popup with "Starter package" shows up. I have enough crystals though.. Any ideas? Do I need to spend my lovely 10boosters just to get event rewards?
