Improved Critical

With your chosen weapons, you know how to hit where it hurts.

Prerequisites: Weapon Focus, base attack bonus +8.

Benefit: When using any weapon with which you have Weapon Focus, your threat range is doubled. For example, a longsword usually threatens a critical hit on a roll of 19–20 (two numbers). If a character using a longsword has Improved Critical and Weapon Focus (longsword), the threat range becomes 17–20 (four numbers).

Special: The benefit of this feat stacks with the effects of the keen edge spell or the keen weapon property. (Remember that two doublings is a tripling, etc.) It may or may not stack with other effects or abilities that increase a weapon’s critical threat range; see individual ability descriptions for details.

A fighter may select Improved Critical as one of his fighter bonus feats.
