i dont understand .... are you looking for a Simple easy to play Build ?....... since you said she was a NEW player
Both my Co-DM and I have agreed that pretty much all 3.5 sources are viable. No real restrictions. Besides keeping the build simple, the only other real constraint is keeping/making the build as pretty as it can possibly be.
the build you made was nice ..... but
Very Far from Simple, and has Options that a New Player wont understand how to use ...... chances are that more optimized players might get Impatient if she is unable to use the build Properly(or in a way you might use it)
for a Simple Build...... dont even think about Spellcasting.....
a Simple Build might be like this:
Succubus 12/ Marshal 3/ Master Thrower 5focus on Cha .... assuming 32pt buy:
12 Str
30 Dex
16 Con
20 Int
18 Wis
40 Cha
Master Thrower tricks:
Palm Throw
Trip Shot
Weak Spot
Marshal Auras:
Motivat Cha
Motivate Dex
Feats:
Skill Focus(Diplomacy)(marshal bonus)
Point Blank Shot
Precise Shot
Weapon Focus(Dagger)
Weapon Finnesse
TWF
Quickdraw(MT bonus)
Imp Crit(MT bonus)
Snatch Arrows(MT bonus)
Combat Panache
Assume Supernatural Ability(Greater Teleport) would be nice also if you wanted to switch something out
this build gives great survivability .... and she can contribute to each combat(Battlefield Control and Debuff(Penalty to Attack roll = Cha bonus), and even more out of Combat with a focus on Diplomacy(50+ check) and Bluff.... also she boosts everyone else at the same time.....
she can be anyone(Change Shape (SU) ability, unlimited duration or uses), at will Charm Monster(DC 32), Detect Thoughts,Suggestion, Greater Teleport
SR, DR, Imunities, resistances , Flight... etc....
what does she need spells for...... she can just run around being Pretty(Diplomacy,Bluff) and Trip everything that comes near your Party(10 attacks(using Gloves of Balanced Hands) Ranged Touch Attacks with Dex check of 1d20+29, can be a lot higher if needed)
very simple ... but she has the Important options that she needs to help the rest of any Party
