"The Impaler"

 is a type of Ground Weapon acquired exclusively in Q's Winter Wonderland.

This weapon-like contraption appears to be fueled by some sort of Q-Continuum psuedo-science. At the moment the trigger is pulled, moisture from the attached tanks is instantly flash-frozen into a crystal shard and propelled toward the intended target at high velocity.

Basically, it's a sniper rifle that launches icicles. Watch out for the eyes.

This weapon only functions while visiting Q's Winter Wonderland and can't cause critical damage.
