Shadowshifter: At 1st level the nocturnal predator gains the Alteration sphere and Dark sphere as bonus magic talents. The nocturnal predator uses his class level as her caster level for the Dark sphere and Alteration sphere. This stacks normally with caster levels gained from other sources. He also gains the Lycanthropic drawback and the Photophobic Casting drawback, but no bonus talents. If the nocturnal predator already has the Alteration sphere from another source, he does not gain the Lycanthropic drawback. If the nocturnal predator already has the Dark sphere from another source, he does not gain the Photophobic drawback. This modifies shapeshifter.
Hidden Transformation: When within an area of dim light, darkness, or supernatural darkness, the shifter may use the Alteration sphere to apply a shapeshift to herself and only herself as a move action. Maintaining this effect through concentration only requires a move action each round as long as the nocturnal predator begins its turn in an area of dim light, darkness, or supernatural darkness.
This ability modifies and counts as quick transformation.
Sneak Attack: At 3rd level, if a nocturnal predator catches an opponent unable to defend itself effectively from his natural attacks, he can strike a vital spot for extra damage. The nocturnal predator’s natural attacks deal extra damage any time his target would be denied a Dexterity bonus to AC (whether the target actually has a Dexterity bonus or not), or when the nocturnal predator flanks her target. This additional damage is 1d6 at 3rd level, and increases by 1d6 every 3 levels thereafter.
Should the nocturnal predator score a critical hit with a sneak attack, this additional damage is not multiplied. A nocturnal predator may only make sneak attacks using his natural attacks. A nocturnal predator may deal nonlethal damage with a sneak attack if the natural attack he is using deals nonlethal damage, including by taking a -4 to the attack roll. Ranged natural attacks can count as sneak attacks only if the target is within 30 ft.
The nocturnal predator 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 nocturnal predator cannot use sneak attack while striking a creature with concealment.
This replaces endurance and enhanced physicality.
I Am the Night: At 1st level the nocturnal predator gains a bonus to Stealth equal to 1/2 his class level and Nightvision as a bonus Bestial trait.
At 10th level a nocturnal predator can use the Stealth skill even while being observed. As long as he is within 10 ft. of an area of dim light or darkness, a nocturnal predator can hide himself from view in the open without the need for cover or concealment. He cannot, however, hide in his own shadow.
This replaces wild empathy, steal language, boundless communication, and endless communication.
