Skill Bonuses

Variants of the St4ckbot mod will distribute an additional 5 bonus skill points across the following skills:

Hunter's Eye can obtain a bonus between 0-5 while The Fast and the Furryous and Pack Tactics can obtain a bonus between 0-3.


  • Fade Away and Megavore critical hits will give FL4K a stack. Weapons that fire multiple projectiles per shot will gain a stack for each projectile that scores a critical hit.
  • Damage that won't reset the St4ckbot's stacks include missed shots, shield effects (except reflect), melee attacks, the Face-puncher, artifacts, or hitting an immune enemy. Reflect shields, the Hunter-Seeker grenade mod, Tediore reloads that spawn bullets, and non-critical hit splash damage from a gun (such as the O.P.Q. System's spawned explosions) will reset the St4ckbot's stacks.
    • While using the War Loader pet, any Hunter-Seeker grenades thrown by the loader will reset the stacks.
  • While using the Lucky 7 pistol, the player can reload until they get the critical hit bonus. Then, using the Bloody Harvest exclusive Terror Anointment that grants ammo regeneration while terrified, the weapon's magazine can be refilled without reloading, thus always dealing critical hits. Because every hit is a critical hit, the St4ckbot will always grant 495% bonus damage, providing excellent synergy,
