I want to create a mundane (at least by classes) Vampire. It will be gestalt, one side is allowed to take LAs and racial HD while the other takes class levels of Tier 5 classes (I intend to go with Ninja).
I just read
this strange Errata because the WotC side actually gives me the Complete Mage Errata whenever I try to download the official ToB errata. So my first question would be how official are these Erratas on Iron Heart Surge?
Then, what would a Vampire needs to be playable?
Just to recall it, here are the Vampire's Weaknesses from the SRD:
Repelling a Vampire
Vampires cannot tolerate the strong odor of garlic and will not enter an area laced with it. Similarly, they recoil from a mirror or a strongly presented holy symbol. These things don’t harm the vampire—they merely keep it at bay. A recoiling vampire must stay at least 5 feet away from a creature holding the mirror or holy symbol and cannot touch or make melee attacks against the creature holding the item for the rest of the encounter. Holding a vampire at bay takes a standard action.
Vampires are also unable to cross running water, although they can be carried over it while resting in their coffins or aboard a ship.
They are utterly unable to enter a home or other building unless invited in by someone with the authority to do so. They may freely enter public places, since these are by definition open to all.
Slaying a Vampire
Reducing a vampire’s hit points to 0 or lower incapacitates it but doesn’t always destroy it (see the note on fast healing). However, certain attacks can slay vampires. Exposing any vampire to direct sunlight disorients it: It can take only a single move action or attack action and is destroyed utterly in the next round if it cannot escape. Similarly, immersing a vampire in running water robs it of one-third of its hit points each round until it is destroyed at the end of the third round of immersion. Driving a wooden stake through a vampire’s heart instantly slays the monster. However, it returns to life if the stake is removed, unless the body is destroyed. A popular tactic is to cut off the creature’s head and fill its mouth with holy wafers (or their equivalent).
Helpful would be ways via Race/Templates/Magic Items to reduce the effects of the Vampire's Weaknesses.
I.e. the Aporter Armor enchantment helps from beeing destroyed by water or sunlight, Boots of Teleportation help on an ocean.
Suggestion makes people invite you into their home, while ranged stunning attacks would get rid of people holding me at bay.
Turning of their own scent would get rid of the Galic odor weakness.
Also, casting a darkness in public helps from beeing slain by sunlight.
And since I loose 1/3 of my HP in running water, I would get more time before I die when I have some sort of Fast Healing. Acid Immunity + Water to Acid would help, too.
