Advanced Potion Shop Robbery

This is a good workaround when the shop's walls prove un-diggable. Thanks to Yulgash for sharing his secrets.

The Hiest

This works just for the Potion shop located in the Borderland Settlement

1. Obtain a Potion of Unholy Water (dropping a Potion of Water on a non-aligned altar can achieve this, but it can go wrong if the deity gets angry. So best do it in the nude with an empty backpack.
   
   
2. Get dressed now. You're becoming an embarrassment
   
   
3. Stand in the Potion Shop doorway and drop-sell a non-cursed potion YOU own (preferably an uncursed Potion of Water or Holy Water)
   
   
4. Pick it up again and 'dip' it into your putrid Unholy Water. The shopkeeper complains bitterly about the damages
   
   
5. DROP the now-cursed potion
   
   
6. Walk one square out of the shop to the map-edge (you're in real trouble now if you forgot to drop that potion)
   
   
7. Stock damage incurs a debt to the Merchant Guild, so the Shopkeeper moves to the doorway to body-block vandals the likes of you.
   
   
8. Leave town, shopkeeper will follow
   
   
9. Leave him in CoC, preferably locked up in the first room for his own protection.
   
   
10. Now back to town to pick up your free potions!
    
    
11. Collect shopkeeper from CoC, take back into town, he'll run back to the shop and periodically restock as normal
    
    
12. And why not stash a bottle of Unholy-water in a locked room next to the shop to avoid any further Altar-anxiety?
    
    
13. Repeat your crime spree whenever they restock
