Bane

Bane is a 1-Energy Silent attack that deals 7 damage (10 upgraded) and deals 7 more damage if the target is Poisoned (10 more upgraded). Against a Poisoned enemy, Bane effectively deals 14 damage (20 upgraded) for 1 Energy — exceptional efficiency that rivals the best attacks in the game. Poison is a core mechanic for many Silent builds, so Bane fits naturally into poison-focused strategies.

Bane is strong because even 7 damage for 1 Energy is above vanilla attack efficiency, and the conditional doubles it against Poisoned enemies. With Deadly Poison, Noxious Fumes, or Poisoned Stab applying Poison early, Bane becomes one of the highest-damage 1-Energy attacks available. Upgraded to 10/10, it deals 20 to Poisoned targets. A high pickup in any poison-focused Silent run.
