Hi!
Increase the number of character slots to 1200-1500.
Add Sands of Blood to the "Frontier" and "Iron Coins" stores.
1 SoB for 1000 frontier coins (14 per week)
1 SoB for 1000 iron coins (7 per week)
Add options to buy more than one item from the store at a time. It is very troublesome to scroll through the entire store looking for the last item in the order. Or divide the store into more topics.
Add options to open more than 99 souls at a time. And so it goes through them then sacrifice.
