Overview

T.K's Wave is a simple but classic high damage Legendary Shotgun, returning from Borderlands' past. It shoots a wave of ten pellets that bounce and spread throughout the air.

While it's not super effective from a distance (as it's hard to land multiple projectiles), firing up close is sure to do some major damage.
