Hopping Stride 
Feat 5
Source Pathfinder Lost Omens Ancestry Guide
Prerequisites Ru-Shi
You've internalized the hopping gait of your vampiric forebear. Stride up to a distance equal to your Speed - 10 feet. During this Stride, instead of moving through each space normally, you hop over every other square between your starting space and your ending space. These hops aren't high enough to jump over a creature or other significant obstacle in your way, but they avoid difficult terrain, hazardous terrain, pressure plates, or hazards on the ground or up to a foot above it in the spaces you hopped over.

Necromantic Physiology Feat 5
Source Pathfinder Player Core 2
Your unusual physiology has developed in a way that makes it difficult for parasites and other infestations to prey upon you. You gain a +2 circumstance bonus to saving throws against diseases. If you roll a success on a saving throw against a disease, you get a critical success instead. If you have a different ability that would improve the save in this way (such as the Battle Hardened fighter class feature), if you roll a critical failure on the save you get a failure instead.

Taste Blood Feat 5
Source Pathfinder Lost Omens Ancestry Guide
Prerequisites Cel Rau, Straveika, Svetocher, or another lineage from a vampire with the Drink Blood ability
You retain not only your vampiric parent's taste for blood but their ability to gain vitality from it. You drink fresh blood from a living humanoid creature, gaining temporary Hit Points equal to the target's level that last for 10 minutes. The target must succeed at a fortitude save against the higher of your class or spell DC or become Drained 1. Regardless of the outcome of this save, the target is temporarily immune to your Taste Blood for 1 day; further uses of this ability against the target don't increase the drained condition or grant you more temporary Hit Points.
To drink a creature's blood, either your last action must have been a fangs Strike that damaged the target, or the target must be Restrained or Unconscious and your last action must have been a Strike that dealt piercing or slashing damage to them. If the target is willing, they don't need to be restrained or unconscious for the latter.
Draining the life force from an unwilling humanoid creature is a greater violation than just drinking their blood. Taste Blood has the evil trait unless the target is willing or is an active foe in combat.

Undead Companion Feat 5
Source Pathfinder Lost Omens Ancestry Guide
Prerequisites an animal companion or familiar
Your companion is also touched by undeath, a mix of a traditional companion and a skeleton, zombie, or stranger form of unlife. Your companion gains the undead trait instead of the animal trait and gains void healing. It otherwise uses the normal rules for an animal companion or familiar; that means it can still be affected by many conditions or effects to which most undead are immune.

Source Pathfinder Player Core 2
Your knowledge of your own not-quite-living anatomy, combined with your experience in combat, helps you take down undead foes with ease. Against undead creatures, you gain a circumstance bonus to damage with weapon and unarmed Strikes equal to the number of weapon damage dice for the Strike. This bonus increases to double the number of weapon damage dice if your target has the vampire trait.

Slip Into Shadow Feat 9
Source Pathfinder Lost Omens Ancestry Guide
Prerequisites ability to cast at least one spell with the darkness trait
Your shadow magic bleeds into the space around you. Whenever you cast a spell with the darkness trait, a lingering aura of shadows reduces bright light within a 5-foot emanation around you to dim light until the end of your turn. Like in natural dim light, you can use these shadows to Hide, but the aura still makes your overall position obvious, so you can't become Undetected through the use of these shadows alone.

Daywalker Feat 13
Source Pathfinder Lost Omens Ancestry Guide
Whether through painstaking exposure, devoted prayer, or simple luck, you've found a greater affinity for life through the sun's light. When in an area of direct natural sunlight, your void healing is suppressed, meaning you are healed by vitality healing effects and harmed by void energy.

ConcentrateAn action with this trait requires a degree of mental concentration and discipline.
DhampirA creature with this trait has the dhampir versatile heritage. These humanoids are the offspring of vampires and members of other ancestries.
DivineThis magic comes from the divine tradition, drawing power from deities or similar sources. Anything with this trait is magical. A creature with this trait is primarily constituted of or has a strong connection to divine magic.
PolymorphThese effects completely transform the target into a new form. A target can't be under the effect of more than one polymorph at a time. If it comes under the effect of another, the second effect attempts to counteract the first. If it succeeds, it takes effect, and if it fails, the spell has no effect on that target. Any Strikes granted by a polymorph effect are magical. Unless otherwise stated, polymorph spells don't allow the target to take on the appearance of a specific individual creature. If you take on a battle form with a polymorph spell, the special statistics can be adjusted only by circumstance bonuses, status bonuses, and penalties. Unless otherwise noted, the battle form prevents you from casting spells, speaking, and using most manipulate actions that require hands. (If there's doubt about whether you can use an action, the GM decides.) Your gear is absorbed into you; the constant abilities of your gear still function, but you can't activate any items. You lose your Speeds and gain those of the battle form. If a polymorph effect causes you to increase in size, you must have space to expand into or the effect is disrupted.
Symphony of Blood Feat 17

You call forth the blood of your foes to grant you vigor. You can cast Vampiric Exsanguination as a 7th-rank divine innate spell once per day.

Twist Healing Feat 17
Source Pathfinder Lost Omens Ancestry Guide
