Darting Viper (Feat)

You can wield your exotic weaponry in ways that even masters of the weapon are amazed at.

Prerequisites: BAB +4, proficiency with an Adaptive Reach weapon

Benefit: Whenever you change your Adaptive Reach weapon from normal to a reach weapon, or vice versa, you gain a +2 circumstance bonus to your next attack roll.

Note: When fighting size Large of larger foes, you can choose which square of their space to target once per round. If that square allows you to change your weapon to or from a reach weapon, this feat grants you a +2 bonus on your next attack after you switch, as normal.
