Is "A cask of ice brewed ale" for anything?

[Petoffen]

You can make the item, but I haven't found any use for it... is it for a quest?

The various "A Cask of XXXX" items are the 8 charge versions of the "A Bottle of XXX" brewed LDoN Drinks that have an Intoxication Effect. The Intoxication effect by some reports gives you a running speed boost. Please note, other running speed buffs have been reported to overwrite the intoxication boost.

THEY DO NOT STACK (based on reports).

The Database shows them as "Unknown" currently, due to the database wipe, and not having the information reloaded yet.

Please note, if someone has the casks, please post the Right-Click information and I will get it re-loaded.

The effect is an increase in movement speed of 1-5% and an unknown effect. Here is the Lucy link.
