Dwarven Mug

One in four mugs of ale you drink from this mug
will be magically transformed into the very finest nonmagical
dwarven ale. If your relationship with the mug is good, the
variety might even suit your current mood and the odds of
getting a good brew might improve in your favor. But really,
who’s going to complain about putting down a second, or even
third, mug for the chance to get a taste of the best stuff? When
that excellent ale does show up, you can share a sip or two
with a friend, but other attempts to capitalize on this mug’s
magic will just shut it down until it can find a more suitable
owner. Quirk: Speaks in dwarven, especially while drunk, even
if ordinarily unable to speak dwarven.
