We have a new artifact that can be purchased from Qeddwyn, CASKS!

Casks are used to store elixirs, salves, and venoms. Their liquids are
not accessible directly, but casks can be used to refill any vial. Casks
can be filled by filling them from a pot or cauldron, or by milking
directly into them. Casks can be set up in stockrooms to sell refills
through shops directly. Casks can hold up to 60,000 refills.

Commands:
------------------------
FILL <cask> FROM <pot or cauldron>
- This will take the liquid contained in the pot or cauldron and
deposit into the cask.

MILK VENOM INTO <cask>
- This will put a single refill into the cask. The balance required to
to this is much more then milking into a vial as it adds an entire
refill.

FILL <vial> FROM <cask>
- These commands will fill a vial from a cask. There is a very short
balance requirement. Those with transcendent concoctions will add
an extra 10 sips to the vial.

FILL <vial> WITH <liquid type>
- This command will search your inventory for a cask containing the
type of liquid specified and refill your vial with it.

PRICE <cask> <price> [SHELF <#>]
- This command is for shopkeepers only. It will set the cask to allow
refills at a certain price.

REFILL <vial> FROM <cask>
- This command can be used in a shop to refill your vial.

REFILL <vial> WITH <liquid type>
- This command will search the shop you are in for a cask containing
the type of liquid specified and refill your vial with it.
