From on high and from far away, you precisely land your shots.
Prerequisite(s): Weapon Focus, BAB +3.
BENEFIT
You gain a TP Pool, which begins at 0 and maximizes at 30. For each successful crossbow or firearm attack you make or get struck by a melee or ranged attack, you gain 1 TP. At 10 TP or more, you may spend all TP to deliver a special crossbow or firearm attack that takes the place of an attack in a full-attack or just a single attack. This attack deals damage as normal + 2d6 damage, and negates the penalty for firing into your second range increment. At 20 TP or more, you may spend all TP to deal normal damage + 4d6 damage, and negates the penalty for firing into the third range increment. At 30 TP, you may spend all TP to deal normal damage + 6d6 damage, and negates the penalty for firing into the fourth range increment. This TP Pool lasts until you sleep for the night, in the morning, it empties out. In addition, your crossbow or firearm attacks deal an additional point of damage for each weapon skill feat in this line that you have.
Special: When used with the Sniping action (found under Stealth), you reduce the penalty to your Stealth check by half (this cannot reduce the penalty below -5).
