[3.5/PF Feat] Tantric Preparation (Please P.E.A.C.H.)

[The Witch-King]

2 questions, is this then sexmagic?

Yes.

and 2 why not divination?

Divination is usually portrayed as something requiring meditation and calm so that the character can receive energies, portents, etc. from "the beyond". The divination and necromancy schools cannot benefit from tantric preparation because the raising of life energies within the casting subject is akin to shining a light into a camera lens, thus preventing effective divination, and likewise, the raising of life energies in the caster interferes with the gathering and focusing of those energies necessary for the casting of necromantic spells.
