Precision

This feat grants +4 on to-hit rolls but damage is halved. It has a cooldown of 30 seconds.

Tips
Due to the significant damage penalty, Precision is typically only useful for enemies that you otherwise would miss on an 18 roll. However, if your weapon has a bonus damage effect that is not halved, then Precision can be more widely useful. It may be especially good when you have a limited supply of high-damage projectiles (such as Dragon-bane arrows) and don't want any to be wasted.

Open question: is Sneak Attack damage halved by this feat? If yes, then Precision is mostly a net reduction in damage-per-second. But if not, then Precision will be very powerful, and a good idea for level 1 rogues to take at creation.

The assumption was that since the 2x multiplier from a critical hit doesn't apply to elemental, bane, or sneak, that the 1/2 Precision multipler wouldn't apply either. But that might be wrong.

Prerequisites: Dexterity 13+, base attack bonus of +1 or higher
