Silent Flight I

Feat Description
This feat allows the Ranger to fire off a single arrow at an unaware target; causing significant damage and possibly stunning the target. The damage done is equal to normal arrow damage + an amount of damage equal to the archer's full dexterity score. While these additional arrows do not do the bonus damage, they each have potential to score a Critical strike. The target must save versus Will (DC=16) or be dazed for 2 rounds. If the target suffers damage during that 2 rounds, he will recover immediately from the daze effect. This special attack has a 10 minute cooldown.
