Studied Target (Ex): A slayer can study an opponent he can see as a move action. The slayer then gains a +1 bonus on Bluff, Knowledge, Perception, Sense Motive, and Survival checks attempted against that opponent, and a +1 bonus on weapon attack and damage rolls against it. The DCs of slayer class abilities against that opponent increase by 1. A slayer can only maintain these bonuses against one opponent at a time; these bonuses remain in effect until either the opponent is dead or the slayer studies a new target.
If a slayer deals sneak attack damage to a target, he can study that target as an immediate action, allowing him to apply his studied target bonuses against that target (including to the normal weapon damage roll).
At 5th, 10th, 15th, and 20th levels, the bonuses on weapon attack, damage rolls, and skill checks and to slayer DCs against a studied target increase by 1. In addition, at each such interval, the slayer is able to maintain these bonuses against an additional studied target at the same time. The slayer may discard this connection to a studied target as a free action, allowing him to study another target in its place.
At 7th level, a slayer can study an opponent as a move or swift action.

Track (Ex): A slayer adds 1/2 his level (minimum 1) to Survival skill checks made to follow tracks.
---
Slayer Talents: As a slayer gains experience, he learns a number of talents that aid him and confound his foes. Starting at 2nd level and every 2 levels thereafter, a slayer gains one slayer talent. Unless otherwise noted, a slayer cannot select an individual talent more than once. Talents marked with an asterisk add effects to a slayer’s sneak attack. Only one of these talents can be applied to an individual attack, and the decision of which to use must be made before the attack roll is made.

Sneak Attack: At 3rd level, if a slayer catches an opponent unable to defend itself effectively from his attack, he can strike a vital spot for extra damage. The slayer’s attack deals extra damage anytime his target would be denied a Dexterity bonus to AC (whether the target actually has a Dexterity bonus or not), or when the slayer flanks his target. This additional damage is 1d6 at 3rd level, and increases by 1d6 every 3 levels thereafter. Should the slayer score a critical hit with a sneak attack, this additional damage is not multiplied. Ranged attacks can count as sneak attacks only if the target is within 30 feet.
With a weapon that deals nonlethal damage (like a sap, whip, or unarmed strike), a slayer can make a sneak attack that deals nonlethal damage instead of lethal damage. He cannot use a weapon that deals lethal damage to deal nonlethal damage in a sneak attack, not even with the usual –4 penalty.
The slayer must be able to see the target well enough to pick out a vital spot and must be able to reach such a spot. A slayer cannot use sneak attack while striking a creature with concealment.
