Evasive

Dodge like a rogue (with min 1 grit)!

Prerequisite(s)

Gunslinger level 15

Benefits

Evasive (Ex): At 15th level, when the gunslinger has at least 1 grit point, she gains the benefit of the evasion, uncanny dodge, and improved uncanny dodge rogue class features. She uses her gunslinger level as her rogue level for improved uncanny dodge.

This means that:

If she makes a successful Reflex saving throw against an attack that normally deals half damage on a successful save, she instead takes no damage. (evasion)

The character can no longer be caught flat-footed, nor does she lose her Dex bonus to AC if the attacker is invisible. She still loses her Dexterity bonus to AC if immobilized. (uncanny dodge)

the character can no longer be flanked. This defense denies another rogue the ability to sneak attack the character by flanking her, unless the attacker has at least four more rogue levels than the target does. (improved uncanny dodge)
