Mechanics

Punches and Swings
What Happens: Vile Prototype will always try to stay in melee and throw extremely hard hitting haymakers.
What to do: Don't let him get up close and roam around the arena to always keep a safe distance. Use the platform in the middle or corners to get up and away from him.
All brawns and no brains.
Javelin Toss

Tips & Tricks
Always make sure to shoot at the Eridium Crystal parts of Vile Prototype as well as the Vile Ordonite around him. Otherwise you won't be able to deal damage to him.
Use AoE or Grenades as they have a bigger hitbox and can deplete the Eridium Crystal bar way faster.
Use 🔥Incendiary weapons once you depleted the Eridium Crystal baras Vile Prototype has a Flesh healthbar which is weak to it.
The platform in the middle and stairs in the corner can disrupt the boss's pathing when he's running at you, buying you some time.
Always backpedal and never stand still while fighting the boss.
There are flying drones up by the roof that can offer Second Wind and Kill Skill synergies. Use the red dots on your radar to locate them.
