Dark LegacyBuy more item slots for your shop.
An item slot is a single space in a shop for a stack of items. For instance, 500 potions of the same type are counted as one slot. As an exception, a bag containing items is also counted as one slot. When a shop opens it has 10 available item slots. When all the slots are taken the shop cannot hold any new item stacks.
You can buy additional slots for your shop by typing 'SHOP STORAGE'. This will increase your item slots by 1. Each slot costs 750 gold times the number of slots you have now. The maximum is 50 slots (65 for guild shops with the bonus).
The game also finds it under: shop_slots, shop slots.
