Nuclear Sharpness (3.5e Maneuver)

Your blade is so sharp, a glowing edge appears as you start splitting things on an atomic level.

Until the beginning of your next turn your critical threat range is doubled (this does not stack with Keen or Improved Critical) and all critical threats are automatically confirmed. You can even make critical hits and precision damage against things normally immune to critical hits.

Your attacks ignore hardness and damage reduction (except DR/-).
