Vesper Primer+Constant Effects
Danger Sense (Ex)
At 3rd level, a rogue gains a +1 bonus on Reflex saves to avoid traps and a +1 dodge bonus to AC against attacks made by traps. In addition, she gains a +1 bonus on Perception checks to avoid being surprised by a foe. These bonuses increase by 1 every 3 rogue levels thereafter (to a maximum of +6 at 18th level). This ability counts as trap sense for the purpose of any feat or class prerequisite, and can be replaced by any archetype class feature that replaces trap sense. The bonuses gained from this ability stack with those gained from trap sense (from another class).
Uncanny Dodge (Ex)
Starting at 4th level, a ninja can react to danger before her senses would normally allow her to do so. She cannot be caught flat-footed, nor does she lose her Dexterity bonus to AC if the attacker is invisible. She still loses her Dexterity bonus to AC if immobilized. A ninja with this ability can still lose her Dexterity bonus to AC if an opponent successfully uses the feint action against her.
If a ninja already possesses uncanny dodge from a different class, she automatically gains improved uncanny dodge instead.
Improved Uncanny Dodge (Ex)
At 8th level, a ninja can no longer be flanked. This defense denies another ninja (or rogue) the ability to sneak attack the ninja by flanking her, unless the attacker has at least four more ninja (or rogue) levels than the target does.
If a character already has uncanny dodge from another class, the levels from the classes that grant uncanny dodge stack when determining the minimum ninja (or rogue) level required to flank the character.
You have a terrible fear of the public at large, a group, or an important person (such as your order of knights, your liege lord, your family, or your lover) learning a shameful truth about you. You take a -1 penalty on saving throws against fear effects, and the DC of any Intimidate check to demoralize you is reduced by 1. If you would normally be immune to fear, you do not take these penalties, but instead lose your immunity to fear (regardless of its source).
If exposed to any effect that normally allows her to attempt a Reflex saving throw for half damage, you takes no damage with a successful saving throw and half damage on a failed saving throw.
Whenever you’re below 0 hit points, you automatically stabilize without needing to attempt a Constitution check. If you have an ability that allows you to act while below 0 hit points, you still lose hit points for taking actions, as specified by that ability. Bleed damage still causes you to lose hit points when below 0 hit points. In addition, you don’t die until your total number of negative hit points is equal to or greater than double your Constitution score.
The fates watch over you. Whenever you are under the effect of a luck bonus of any kind, that bonus increases by 1.
Whenever you spend a hero point to reroll a die roll or to grant yourself a bonus before a die roll is made, there is a chance that the hero point is not spent. Whenever you spend a hero point, roll a d20. If the result is greater than 15, the hero point is not spent. You cannot use this Feat when you use the cheat death Hero Point option.
