This mace hides a secret reservoir of quicksilver (also called
mercury by alchemists) that runs along the interior of the mace in a
slender channel. When the mace is vertical, the mercury swiftly
fills the interior bulb in the haft, but when swung, the heavy liquid
flows out into a mace-head making it heavier. In nonproficicient
hands,
this shifting mass penalizes the weilder by an additional -2 penalty
to attack rolls, beyond the normal nonproficiency penalty for using
an exotic weapon untrained.
