Ok since reading the recent palladin build topic, and discussing the Ad&d side of the role for spells, stats and how to roleplay the quirks..
I have been hankering after a Tiefling Fighter / thief build pretty much the core class of that race imo, so having the RBP mod I choose the closest in looks and feel that being a daedra seducer.
As I have not bothered playing any non native race in oblivion before ( allways man, mer or beast modded or otherwise ), its going to be fun looking at horns, tails and wings.

This is what I have so far.

Name: Anna ( yes from Torment I know its hardly original but I like the name tbh).
Race: Daedra suducer, Small magicka fortify, resist fire 75%?, weakness to shock / frost 50% and mostly a rogue type build.
BS: Don't know yet but shadow, thief, warrior, lady all sort of fit ( again modded so just go by role ).
Skills: So far sneak, security, light armour, acrobatics, blade, H2h, speechcraft are my go to skills, as Tieflings are suspect sneaks, backstabbers, silver tongued rogues, quick to anger and short to trust.

Quests, Thieves for sure as I also have not done the quests for quite a bit now, but anything devious I would say so loads of un-needed thefts.

Attitude for immersion: again Tieflings are suspect sneaks, backstabbers, silver tongued rogues, quick to anger and short to trust, and play it slightly with a chaotic malevolence.

Quirks:
So far..
Only eats raw meat, or gems.
Leather clothes or dark and grim out fits.
No paying guards escape, or fight thats it.

So any help would be appreciated and thank you in advance.

I don't see where you need help, as you've thought everything out pretty well. You have my clearance, for all it's worth.

For Birthsign I would go with Warrior or Thief, flip a coin for it.

Thanks I think just writting it out helps focus me on how to play it to be honest.

I thought a discussion on others view of the race, build, role or general idea will help me flesh out all the kinks in my mind.
To add some other personality for lack of another word, rather than just have me focus on my own views ending up with something that I can toss out when I grow bored.
The last charcter I did this with is one that I plan on backing up and keeping the saves to, rather than start from scratch which is my usual habit.



Lol yes thats a very good idea thanks again Holy Assassin.

New edit:
Went with thief, but looking for a class name what do you think...

Basher,
Cutter,
Indep,
Peeler,
Bobber.
Berk,
Outsider,
Any of those with prefixes like Lady, Knight of, misses.. so on.
