Advice - Drow Noble first daughter of the house Misraria Build

[Shroud05]

My master accepted to let me play a drow noble in an high power evil campaign.
She will be the ambassador of her family in a new world populated by evil being, she is from house Misraria, worships Nocticula and aims to become a demon herself.

I had in my mind a charismatic character with good divine magic end decent combat skills but thematically linked to the drow culture and the demon lords cult.

My issue is building a character that has all the previous traits.
I've tried a crusader build that fulfils the divine caster/fighter and thematic thing but is really poor on face skills (and charisma itself), the battle oracle i feel is noto so well connected to the drow society and many other builds that don't convince me.

So here i'm asking an advice, i don't need a powerful or optimized build with good flavor and i'm open to every solution

ps: sorry for my poor english.

I think you need to consider the various trade-offs involved with each class.

War Priest might be suitable, but if you also want a party face, you'll likely run out of stat points to do it.

So, you need to get as much bang for the buck out of Charisma - making it your main casting stat. And you want divine magic...and you want some fighter capability. Pretty much the Oracle is your go to choice here.

I'd go with Shadow Mystery (thematically apropo w/Nocticula) and choose Tongues as your Curse (Abyssal, of course, once again thematically apropo). Intrigue Mystery might also work extremely well.

Use the Warsighted template to add battle buffs, if you think you need it. If your DM allows, maybe even Ancient Lorekeeper (Drow are elves, after all...) if you want to sneak a few arcane spells onto your spell list.

Eldritch Scion would fit pretty well, except the divine magic bit.
Even better at the "becoming a demon" thing.Also can pick up one of the Obedience feats, and damned disciple for the evangelist boon.

Otherwise, if divine magic is that important, Oracle does look like what you want.

Thank for the advices, i'll try to build something around Oracle and the charisma magus.

Now i'm working on a Crusader focused on Channel energy, Nine Level caster altough less slot spell, hots reasonably hard and has the demon domain. The only drawbacks are the lack of skill points and maybe The need to switch patron to use te rapier as favored Weapon.

For the develop at higher leves i'm thinking about Holy Vindicator or, as you said, evangelist.

With the focus on Channel charisma becomes a focus stat and a drow Noble pb 20 has no multi ability issue.

How do you see this Solution?
