Everflowing Mug

From LSWiki

Random load, probably.

This is is a mug made of brown pottery with a rim made of steel banding. Runes are engraved in the everflowing mug of ale's rim while the brown pottery
is covered in depictions of tavern brawls. It appears to be empty. You estimate its value at about two thousand one hundred gold.  
It is in perfect condition.  
It looks about one and a fifth dimins across and one and seven tenths dimins long.  It weighs about two and a half dekans.
After a moment, the knowledge that the everflowing mug of ale is composed of thirty-one percent pottery, thirty-one percent dweomer, thirty-one percent
steel, six percent ale, and two percent gold drifts into your mind like a long-forgotten memory.

• Draws spiritual energy to create a single drink of ale inside the mug when used as a striking weapon.

You feel your everflowing mug of ale drawing a slight amount of spiritual energy from you.
The runes on the everflowing mug of ale shimmer gently as you hear the distant sounds of revelry.
You pound the greenish-skinned female urga's right leg with your everflowing mug of ale, despite her attempt to parry it with her iron dagger,
though she resists the attack slightly.

Any landed strike will trigger the effect, damage doesn't matter. Being that its use requires you to smack hostiles with it, it may be prudent to change its materials.
