Nevarra: The Age of Peace
Improved Vital Strike (Combat)
Prereq: Vital Strike, BAB +11
Whenever you make a standard action attack or a charge, you now deal an additional amount of damage equal to the weapon dice plus strength. (or DEX if Agile Fighter or other ability) If you are using a weapon in two hands, you instead deal STR and a half. This bonus stacks with Vital Strike
If you are using an unwieldy weapon you now deal triple normal attack damage instead of double.
