Anvillain

 is a gun that fires piercing anvils that knock back and stun enemies.

Trivia

 * The Anvillain is a reference to the Looney Tunes cartoon, Wile E. Coyote and the Road Runner. Anvils were a common running gag within the series, where the lead villain (Wile E.) would order anvils from the ACME corporation in an attempt to catch the Road Runner. ACME delivers their products in crates, much like this weapon.
 * The item's quote and description is an ironic jab to the Coyote's constant failures with catching the Road Runner, which almost always results in his own devices harming himself.
