Bag of Commerce

Description

At first glance, the bag looks like a sturdy leather satchel, reinforced with brass buckles and etched with faint arcane runes. When opened, its interior stretches into a small, perfectly furnished shop or office, complete with shelves, a counter, worktables, and filing spaces — all magically expanded to hold a 10 ft × 10 ft × 10 ft space inside.

• The interior is always clean and organized, with light provided by floating lanterns.

• The bag automatically supplies basic shop furnishings (shelves, counter, small chairs).

• It smells faintly of polished wood and parchment.

Activation

• Opening the bag and speaking the command word expands the interior into its shop/office form.

• Closing it returns all items inside to the bag; the items remain magically preserved.

• Up to 100 pounds of merchandise can be stored safely inside.

Features / Mechanics

1. Portable Shop

   1. The interior counts as comfortable space for working, crafting, or selling.

   2. Characters can conduct sales, manage inventory, or craft items without needing a permanent building.

2. Sales Utility (Optional DM Rule)

   1. When selling goods, a character may roll Persuasion or Insight (DC 12–15 depending on buyer) to determine quality of sale.

   2. Can hold up to 50 individual items for sale at once; prices and gold are tracked magically.

   3. Magical ledger inside automatically records incoming and outgoing funds.

3. Crafting / Workstation Integration

   1. Characters can treat the space as a workshop for crafting items requiring a workbench, alchemy setup, or tools.

   2. Tools must still be present in the bag (e.g., smith’s tools, artisan’s tools).

4. Comfort & Rest

   1. The space is large enough for one creature to take a short or long rest comfortably if desired.

   2. Heat, lighting, and ventilation are magically controlled.

Optional Flavor Effects

• The shop can appear differently depending on the owner’s style: rustic dwarven shop, sleek wizard office, cozy apothecary, etc.

• Patrons may see a faint shimmer around the bag while the shop is open, hinting at its magical nature.

• A tiny magical bell on the counter rings automatically when a customer approaches (friendly notification).

Limitations

• Cannot hold more than 100 pounds in total; overloading may cause magical collapse (DM can roll for mishap).

• Bag cannot function as a full tavern or massive store; intended for personal business or small storefronts.

• Expanding beyond 10 × 10 × 10 ft requires a wish or similar high-level magic.

Roleplay Hooks

• Can be used for smuggling, mobile shops, pop-up markets, or traveling craft fairs.

• Could attract attention from magical regulators or thieves if used in public frequently.

• Allows for creative gameplay: the party could run a temporary business while adventuring.
