"The Incubus and Succubus are actually the same type of creature. The Incubus appears male, and preys exclusively on women; the Succubus appears female, and preys on men. Any one creature of this 
type is capable of manifesting as either gender."Classic: Blood Types pg 95
Note: Magery is listed with spells as that is how Blood Types did nearly all vampire magic. GURPS Update suggested what become the "as advantages" option for Innate Magic available in 4e which is how their "spells" are handled in GURPS Horror.
*Racial Skills: Erotic Art includes +5 for Double-Jointed and +3 for racial skill bonus and Sex Appeal includes +6 for Very Beautiful and +2 for Voice.
====how TET works====
TET 6 is used in Psychic Vampirism indicating this extends the intervals at which you get HP.
IE you don't just prep it, then get the usual 1/second.
Rather you take 1 HP per ATTACK. You are constantly making ATTACK maneuvers.
TET means readies to prep that attack. Or concentrates if you normally need that due to Malediction.
The pricing of the first (-30% tier) of Immediate Preparation Required suggests TET should perhaps be -5% per level which if done would either reduce the discount here to -50% or make it take MUCH longer.
== Edition comparison==
the fluff (flavor text) of Blood Types mentions:
:Their physical bodies may take damage normally, but upon “death” they merely dissipate into spirit form, only to return again.
The 150 point resurrection ability was meant to represent that, which is found on BT63.
This began healing 1 hour after "death". Parts regrow. "remains unconscious until full HT" is similar to how Unkillable 3 works in 4e. The only difference is that here, the body appears to stay like with UK2, not vanish like UK3.
"largest existing pieces reassemble, and the rest will melt into goo" for separated parts falls somewhere in between.
"the vampire is permanently dead (unless capable of existing as a non-corporeal being)" may give Succubi an out since "Insubstantial" allows them to turn non-corporeal.
*this is the same approach of BT97's Lilitu
**in either case sex is not a requirement of leeching HP like in 4e, but rather just something they would do to help lower victims' guards. Lilitu feed via Bite (ie Vampiric Bite) rather than Steal HT.
* this is a different approach to BT104's Vampir who instead used innate magic of Astral Projection and Materialization while being an Astral Entity.
One issue however with this is that each use costs character points, like with Extra Life. That's something not true of classic UK3 in 4e.
To do that, you would need to make it a character point powered ability. This reduces cost to 1/5 and even then, the cost to use a CP-powered ability is merely 1-5 points, not 25.
"these may be taken off anything" somewhat resembles Corruption which may be a better model for doing this.
The 4e version requires ongoing physical sexual contact, the Classic succubus just had innate magic which would only require touch to use like a standard necromancer would do. Sex was merely a way to get their guard down, complimenting charm/enslave/sleep to make victims defenceless.
The 4e version does not have Unkillable 3. Unless it willingly returns to insubstantial form, killing it in material form kills it permanently.
Modifying H27's Threshold Entity metatrait to emulate Classic's desription would be aided by using H16's Reversion enhancement, specifying insubstantial as the native form to revert to at 0 HP.
:"cannot be killed by perils incapable of injuring your native form"
:If such injury would reduce you to 0 or fewer HP, you go to 0 HP and revert
"must remain until fully healed" much emulates how UK3 works. The only difference is that without UK3 you could be killed while in insubstantial form.
This is based on a Classic trait from GURPS Spirits called Spirit Invulnerability on pg 40:
:cannot be killed by damage to their physical forms
:reducing them to 0 HT simply forces them back into spirit form and prevents them from assuming material form again until their lost HT would have fully recovered.
This was different in that it split the HP pools though:
:When the spirit’s physical form is destroyed it automatically returns to spirit form with full normal HT
When it refers to "fully recovered" lost HT, this is the separate HT a material form would have. S35 has FP costs for buying HT (HP in Classic) and ST (FP in Classic) for the material form. Normally how it works:
: If the spirit’s physical form is reduced to 0 HT and it fails a HT roll, it is forced back into spirit form.
It's unclear how damage carryover normally works. PASSING a HT roll would allow it to STAY in spirit form and keep getting injured to negative HP and possibly die?
That's one freedom which is lost via taking "Reversion", there is no freedom to stay substantial in negative HP.
Ectoplasm had no HP in Classic, it's unclear if it could be harmed at all. In 4e it has 1 HP, so it could be harmed. Reversion is tailor-made for that since it's very easy to die in ectoplasmic form despite the Injury Tolerance. It's only a limitation on insubstantial and the only way to have distinct HP pools and injuries is by using Altered Form. That COULD be done though.
How to design that would be taking something like "Uncontrollable" on Insubstantial so it switched you bakc when in danger (not necessarily at 0) and sub HT roll for Will roll to overcome the Uncontrollable limitation.
