Advanced Talents
At 10th level and every 2 levels thereafter, a slayer can select one of the following advanced talents in place of a slayer talent.
A slayer with this advanced talent can kill foes that are unable to defend themselves. To attempt to assassinate a target, the slayer must first study his target for 1 round as a standard action. On the following round, if the slayer makes a sneak attack against the target and that target is denied its Dexterity bonus to AC, the sneak attack has the additional effect of possibly killing the target. This attempt automatically fails if the target recognizes the slayer as an enemy. If the sneak attack is successful, the target must attempt a Fortitude saving throw with a DC equal to 10 + 1/2 the slayer's level + the slayer's Intelligence modifier. If the target fails this save, it dies; otherwise, the target takes the sneak attack damage as normal and is then immune to that slayer's assassinate ability for 24 hours.
Rogue Advanced Talents and Ninja Master Tricks
A slayer can select one of the following rogue advanced talents or ninja master tricks in place of a slayer advanced talent: deadly sneak, evasion, feat, hunter's surprise, knock-out blow, master of disguise, opportunist, or stealthy sniper. A slayer can select multiple rogue advanced talents or ninja master tricks by taking this slayer advanced talent multiple times, but can't select the same one more than once.
A slayer can use the Stealth skill to hide in any of his favored terrains, even if the terrain doesn't grant cover or concealment. A slayer must have the terrain mastery talent to select this talent.
A slayer with this talent may move through any sort of undergrowth (such as natural thorns, briars, overgrown areas, and similar terrain) at his normal speed and without taking damage or suffering any other impairment. Terrain that is enchanted or magically manipulated to impede motion still affects the slayer as normal.
