It's actually a fairly rational fear in this case. – Always Incendiary. Projectiles explode multiple times mid-flight before hitting their target.
Usage & Description
Due to the nature of the projectile, the Pyrophobia is best used in closed areas or catwalks with several enemies in a line. Shooting just over or to the side of enemies will allow it to score hits on multiple enemies. Since the bullets are based on time, not distance, skills that increase projectile speed, such as Maya'sAccelerate or Zer0'sVel0city will decrease the effectiveness of this weapon by causing it to have fewer explosions over the same distance. The Pyrophobia's skin features a charred appearance.
Trivia
Pyrophobia is the irrational fear of fire or flame. This is mentioned in the red text.
The Pyrophobia is very similar to a legendary rocket launcher made by Maliwan in Borderlands, the Rhino.
A hotfix on 10/28/13 increased the reload speed and elemental effect chance on the Pyrophobia and all other Maliwan rocket launchers as part of the Borderlands 2 $100,000 Loot Hunt.
