Gamma Burst is the Action Skill of FL4K's Master skill tree. This skill allows FL4K to create a rift at a target location, and teleport their pet there. The rift deals radiation damage to nearby enemies, while the pet becomes irradiated and deals additional radiation damage with its attacks. Gamma Burst can also revive FL4K's pet, but this will double the followup cooldown time.


  • Damage: varies with character level
  • Duration: 20 seconds
  • Cooldown: 30 seconds



  • Gamma Burst is currently glitched where it prevents FL4K's pets from being crippled when the skill is active.
