Bore is a skill that lets your bullets pierce through enemies dealing bonus damage to subsequent enemies hit. It's description says

Each additional target takes +100% bullet damage

Does this mean the +100% is cumulative (+100% for the second target, +200% to the third target, etc) or is it just a flat double damage after the first? For that matter, is there a limit to how many targets a shot can pierce?

It also mentions this does not affect rockets and other special types of projectiles. What projectiles does it not affect?

    Why would passing through a target make your bullet MORE powerful??

The bonus from piercing is cumulative. Presumably there is some upper limit to the bonus, but I don't know what it is.

  • Yep. Just confirmed. First target takes base damage, second target takes x2, third takes x3.

  • I wouldn't be so sure that there's an upper limit, considering there's a B0re glitch on BNK-3R and other bosses that instantly kills them.
