A player wanted a half-sucbi template in a new campaign that is starting so how about this:
Half-Succubus template
“Half-Succubus” is an inherited or acquired template that can be added to a living, corporeal creature with an Int score of 4 or more. A half-succubus uses all the base creature's statistics and special abilities except as noted here.
CR: HD 4 or less, as base creature +1; HD 5 to 10, as base creature +2; HD 11 or more, as base creature +3.
Alignment: Any
Type: The creature's type changes to outsider (native). Do not recalculate HD, BAB, or saves.
Armor Class: Natural armor bonus improves by +4
Defenses/Qualities: Gains darkvision 60 feet; immunity to poison; acid, cold, electricity, and fire resistance 10; DR 5/magic (if HD 11 or less) or 10/magic (if HD 12 or more); and SR equal to creature's CR + 11 (maximum 35).
Speed: Unless the base creature flies better, the half-succubus flies at twice the base creature's land speed (good).
Special Attacks: A half-succubus gains the following attack.
Vampiric Touch (Su)
An half-succubus gains no claw or bite attack. She does gain a special touch attack usable once per round as a standard action. If she hits, she deals 1D6 points of negative energy damage plus additional damage equal to her Charisma bonus. She gains half of any damage dealt in this manner as temporary hit points. She cannot gain more than her target’s current hit points + the target’s Con score (which is enough to kill the target). The temporary hit points disappear in one hour.
Spell-Like Abilities: A half-succubus with an Int or Wis score of 8 or higher has a cumulative number of spell-like abilities set by its HD. Unless otherwise noted, an ability is usable 1/day. CL equals the creature's HD (or the CL of the base creature's spell-like abilities, whichever is higher).
Hit Dice
1-2 Charm Person 3/day
3-4 Detect Thoughts 3/day
5-6 Suggestion 3/day, Tongues 3/day
7-8 Polymorph (humanoid form only) 3/day
9-10 Dimension Door
11-12 Charm Monster
13-14 Greater Teleport 3/day
15-16 Ethereal Jaunt
17-18 Summon monster IX
19-20 Energy Drain
Abilities: A half-Succubus gains Dex +4,Con +4,Int +2,Cha +6.
Skills: A half-succubus with racial HD has skill points per racial HD equal to 6 + Int mod. Racial class skills are unchanged, and class level skill ranks are unaffected.
Any thoughts,advice (esp on the spell list,hard to choose a good mix for sucbi) and comments are welcome.
