Kinertial Launch

Spend one mana to cast Kinertial Launch.
This spell will increase the inertial mass of an
item, maintaining its velocity. A thrown item
such as a small stone can hit like a bowling ball,
and a bowling ball hits like a cannon.
Only with incredibly high constitution can one
sustain a run during this spell, but even a steady
walk forward carries the impending momentum
of a slow-moving, very massive train.
