Sholop will craft a large sack if he has access to 3 Wolf Pelts. The Small Sack, Large Sack and Backpack are unique because they increase the main inventory, allowing the player to hold more items, including other inventory items. The large sack gives 2 more slots, increasing the main inventory from 4 to 6. Only one sack may be used at a time, be it small or large. Sholop buys large sacks for 155 gold and sells them for 900 and Darklow sells them for 995.
