Precision

Precision grants +4 on to-hit rolls and bypasses 25% fortification, but damage is halved. It has a cooldown of 30 seconds.

Base damage is halved (including damage from Sneak attack), but elemental, burst, and alignment based damage is not.

''Note: There is currently a display bug with Precision when making Sneak attacks. This has been confirmed by a Dev and will be fixed in an upcoming update.''

Tips
The base damage increase is the greatest on monsters that require a 20 to hit without Precision, but require only 16+ to hit with Precision. In this specific case, base damage is 2.5 times higher with Precision, ignoring critical hits (you hit 5 times more often, but deal only half damage).
 * Even though the base damage is halved, Precision can increase your overall damage due to hitting more often, both from the additional weapon damage (elemental, etc.), and in some cases from even higher base damage.


 * Precision can be useful to land more critical hits, if you have a weapon that has special effects on a critical.


 * Precision decreases base damage against extremely high AC monsters that still require a 20 to hit with Precision. Instead, use Power attack against these monsters.


 * Precision decreases base damage against medium to low AC monsters, as the +4 to-hit does not compensate for the base damage being halved.


 * Precision is less effective on monsters with Damage Resistance.


 * Consider using it when you have a limited supply of high-damage projectiles (such as Dragon-bane arrows) and don't want any to be wasted.

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