I almost don’t want you to fix this one…
Step 1: Conquer an area with a loot-able chest (Peasant village for example.)
Step 2: Select “Orders > Claim Tile” on the buildings in the village.
Step 3: Loot the chest.
Step 4: Burn the chest with a fireball.
Effect: Your minions will automatically rebuild the burned chest in it’s unopened/unlooted state.
Step 5: Loot the chest again.
Repeat.
Profit.
For the cost of a few wood… you gain enchanted weapons, armor, scrolls of various kinds, and gold.
