I was thinking of making a BattleMage type build like this...
Elf arcanium or Warforge repair ( -2 charisma hit ) spells possibly drow for better stats if don't have 32 point build
7 Wizard
11 Favored Soul
2 Rogue
Spell List:
1st: Shield - NightShield or Magic Missile - Tumble - Jump - Expeditious Retreat
2nd: Blurr - Resist - Bull's - Owl's/eagle/knock
3rd: Haste - Herioism/Rage - Protection energy
4th: StoneSkin - Remove Curse ( since Favored Souls don't get the spell )
Favored Soul spells - healing -
favored soul: for fighting, Spell Points, clerical buffs and healing
Rogue: evasion
Wizard: Buffs, Extend metamagic, Heighten?
this would have buffs self healing and evasive. Might be a good solo build. I still don't know any spells of favored soul except healing and summoning or feats any information on it would be nice and needed stats. if you try this build in new mod drow 32 pt build would probably be the best. Finesse feat might be needed in this build.
