Halloween tokens after Halloween event
I have Cursed Seed tokens that I don't need as I have done the challenges that I needed them for. I also have Blight Serum that I find is pretty useless, as it uses the same key as other actions such as trappers traps. Both of these items I have had to buy while levelling up on the bloodweb, I had no choice put to spend BP on it.
Once the event is over, will these remain and be no use? Do I have to keep them until next Halloween? Will they be redeemed for BP? Will they be exchanged for something else?
