I already have tyr and Frigg at 3/70, I only have 2 rings and 6 tonics. I’m loving the Halloween heroes, but the fear of summoning victor and already having a red and green that would be fun to ascend is a deterrent for me.
If you don’t have any then Christmas is great for a MN a reviver. I had 30 eht and gems to do 20 pulls. I picked Halloween just for Glenda/Francine and got Francine on number 10. So I’m saving the rest of my tokens and gems for Kramp-mas. If you have Frigg/Tyr I’d say you will benefit from Krampus more he will be a great blue tank.
