At 5th level, a flying blade gains a +1 bonus on attack rolls and damage rolls when using daggers or starknives in combat. When she wields a dagger or a starknife, she gains the benefit of the Improved Critical feat with those weapons. Additionally, a flying blade increases the range increment of a thrown dagger or starknife by 5 feet. This range increment increase stacks with that of precise throw.
At 9th level and every 4 levels thereafter, the bonus on attack rolls and damage rolls increases by 1, and the range increment increases by 5 feet. This ability replaces swashbuckler weapon training.
