Vampire perks

[Bicorn]

I've been thinking of possible perks to offer specifically for vampire characters. Comments/critique? Suggestions for new ones?

Analgesic Bite
Your bite dulls pain; if you're feeding stealthily, the victim will not notice the bite unless they succeed in a Per-2 roll. As an additional effect, if the victim has a Chronic Pain disadvantage or similar condition localised to the body part you bit the pain penalty from the condition is halved for one hour per hit point you consumed from them.

Blood Connoisseur (type)
Your vampiric ability is 50% more efficient when used on a specific sort of victim; i.e. each two points drained from the right kind of victim counts as three. The chosen type should be moderately uncommon among potential targets; e.g. "redheads", "adult female virgins" or "clinically insane people".
(This one might be too strong. Suggestions for toning it down?)

Clean Feeding
Your victims recover from your predations more easily than normal; after feeding they get +2 to rolls to recover the lost hit points and to avoid secondary bleeding, infection etc. from the bite. This bonus ends once all points lost have been recovered, by whatever means.

Corpse Feeder
You can feed on the dead, as long as they're fresh - either recently dead (within an hour or so) or somehow preserved (via freezing, etc; embalmed corpses have no blood.) This is less effective than feeding from a live victim; it takes 10 seconds to heal one hp/fp, and the most you can get from one corpse is equal to one-fifth the maximum hp it had before death.

Exotic Feeding Method
You have an alternate means of drawing blood from a victim; e.g. forming a second mouth in the palm of your hand, extruding hollow sucking needles from your fingertips, or extending out a proboscis. You can also use a normal bite instead, but cannot feed using both methods at the same time.
Each alternate feeding method is a separate perk.
(If you can only feed through the special method, and don't have a regular bite attack, it's just a special effect on the Vampiric Bite advantage and costs no points unless, by GM's judgement, it makes feeding more convenient.)

Pleasurable Bite
Being bitten by you feels good. After you bite someone, you get +2 to social influence skills made for the purpose of persuading them to let you bite them again, not report you to vampire hunters, etc. (Obviously, if you bit them without consent this'll only partially offset a large penalty.)

Subtle Bite
Your feeding leaves much less evidence than usual; perhaps your feeding apparatus makes a neater wound than the typical vampire fangs, or you are able to make the wound close quickly. Noticing the mark you leave on a victim requires a Per-5 roll. (Per-2 on close inspection, or unmodified Per if the examiner is specifically looking for bite marks.) Assuming normal healing rate, every day that passes after feeding gives a further cumulative -1 to the roll.

Vampiric Mimicry
After feeding from someone you gain +2 to Acting, Disguise, and Mimicry rolls made for the purpose of mimicking the victim for one hour per hit point consumed.
