OK this isn't a amazing thread, but it won't get answered in wc and devs will only say get support. What happens with skulls when promo finish's? I mean it's worth 650 bill roughly to a clan and it is potentially a seal that is worth a few bill so I'm told.. some people did try to collect these skulls knowing they would have a use.. so basically a answer would be nice from deV's as to what will happen.
