B0re is a tier 3 skill in Zer0's Sniping skill tree. It allows his bullets to pierce through enemies and gain a massive damage bonus afterwards. B0re does not work with rockets and some special projectiles. While in Decepti0n, B0re also highlights enemy critical hit locations.


  • Bonus Damage Per Enemy Pierced: +100%
  • Enemy critical locations highlighted in Decepti0n.


  • Critical spots always have a number or word next to them; these numbers and words often reference internet slang, such as 1337, LOL, and GTFO.
  • Not all critical hit locations are properly highlighted.
  • B0re works with most gyrojet projectiles from Torgue weapons, and even works on the Flakker's bullets, although given Flakker's low accuracy, this is unlikely to occur.
  • The splash damage from Torgue and Maliwan weapons is applied on every impact. It does not provide any piercing or bonus damage for some E-tech weapons.
  • As B0re's damage bonus is multiplicative, the damage output of even a single, weak projectile can rise exponentially if it passes through multiple hitboxes. Due to this, certain enemies can be killed with very few (or even a single) shot from any gun that B0re applies to. Spiderants and threshers both have forms that allow projectiles to exit and re-enter them to deal bonus damage. BNK-3R, Hyperius the Invincible and 010011110100110101000111010101110101010001001000, and their turrets and minions, have multiple overlapping hit boxes that allows the damage to multiply several times.
  • If a player respecs Zer0's skills after taking B0re, the bullet piercing effect will remain but the bonus damage and critical highlights during Decepti0n will be removed.
  • B0re allows bullets to pass through surveyor and constructor reflector shields, as well as the ones used by Hyperius the Invincible and his minions. PWR Loaders that have their arms spun up will also be unable to reflect the bullets. B0re bypasses most, if not all, forms of bullet reflection, including that of Jackenstein and Badassasaurus Rex.
  • The Twister is extremely effective with B0re as the whirlwind pattern can cause the pellets to exit and re-enter enemies multiple times, greatly increasing its damage.
  • Many enemies, including large enemies such as Saturn, will stagger sideways when hit by a B0re shot (a shot that has gone through at least one hitbox).
