'Acetum Primus' is the third and most powerful of the known acid
disciplines at the Mage's disposal.  This incantation pulls forth the
strongest caustic agents in the casting Mage's neighboring planes,
and propels them in a tight cyclone-like blast towards the Mage's
chosen victim.  The cross-dimensional disturbance, the physical
violence, and the bonescouring potency of the conjured compound all
work together to effect an estimable estrapade.
