Vampiric Touch (Su)

At 1st level, you gain a slam attack that deals 1d6 hp damage, and your successful slam causes mortal creatures to bleed. This is as the cantrip, but affects non-dying creatures (1 hp/round until healed or stabilized by the Heal skill). You can use this ability a number of times per day equal to 3 + your Charisma modifier.

You also gain darkvision 30 ft.

Vampiric Power (Su)

At 3rd level, you gain DR 5/ silver, resist cold and electricity 10, and you no longer have a reflection in a mirror or cast a shadow. You can use beast form II as a spell-like ability (dire rat, dire bat, or wolf) three times per day.

Vampiric Swarm (Su)

At 9th level, you can summon rats, bats, or wolves, as per the children of the night special attack in the vampire's stats in the Pathfinder Bestiary.

Your darkvision increases to 60 ft.

Vampiric Mist (Su)

At 15th level, you gain the ability to assume gaseous form at will as a standard action (caster level 9th), but can remain gaseous indefinitely with a fly speed of 20 ft. with perfect maneuverability.

Death Supreme (Su)

At 20th level, your vampiric nature becomes complete. You no longer have a pulse or a body temperature. You gain DR 10/silver, immunity to poison, paralysis, and sleep attacks, as well as fast healing 2. Undead creatures consider you one of their own unless you attack them. You also gain the slam, blood drain, and domination attacks of a true vampire.
