Oh yeah, you're right. More room to play around in then.
Anyway, returning to the original build, I was able to work things out with my DM and we came to these resolutions.
1) We've agreed to adapt the Rainbow Servant class to worship another outsider: a Solar. Doing so, we've changed the bonus Domains to the following: Sun, Air, and Good. We've renamed the class to the Radiant Servant.
2) I am allowed to trade spells on the existing Beguiler spell list for spells on the Sorc/Wiz list provided that (1) the number of spells I replace per spell level does not exceed 2/3 of the total number of spells listed for that level, (2) the substitute spell must match the substituted spell in both level and school, and (3) I can only swap spells of the Illusion, Enchantment, or Divination school.
These game birth to the following build: The Black Sun
Name: Kiaroskuro Brightshadow (the name is Greek for "Interplay of Light and Shadow")
Stats: Str 8, Dex 12, Con 12, Int 18, Cha 17, Wis 11
Illuminian (Aesh-Krau) Beguiler 1 / Rainbow Servant 10 / Contemplative 1 (Planning Domain) / (Non-Racist) Shadowcraft Mage 3 / Sacred Exorcist 1 / Radiant Servant of Pelor 1 / Mindbender 1 / SCM 2 /
Feats: Assumes 2 Flaws
ECL 1 (3) Precocious Apprentice, and Improved Krau (Early Qualification for Rainbow Servant), Extend Spell (Retrained to Heighten Spell at ECL 12)
ECL 3 (1) Persistent Spell
ECL 6 (1) Versatile Spellcaster
ECL 9 (1) Residual Metamagic
ECL 12 (2) Spell Focus: Illusion, Extend Spell
ECL 15 (1) DMM:Persistent (Delayed until 16th level)
ECL 18 (1) Extra Turning
Build Benefits:
- Extremely versatile and powerful spontaneous casting capable of responding to almost any situation or demand on the fly:
---- Capable of spontaneously casting any spell from the Cleric spell list by ECL 11
---- Capable of spontaneously casting Shadow Evocation or Shadow Conjuration and mimicking any Soc/Wiz Evocation, Conjuration (Creation and Summoning) spell of the appropriate spell level by ECL 15.
---- Potent Shadow spells (mimicked spell's level + 30% quasireality)
---- Shadow spells extended by default
---- Multiple ways of multiplying higher level spell slots (Versatile Spellcaster + Residual Metamagic)
- Illuminian Aeshkrau Power Word allows us to use Str instead of Int to determine bonus spells. Great with some Draconic Polymorphing
- +2 Racial bonus on saves against Shadow spells
- Great spell Persisting capabilities by ECL 16 and peaks at ECL 17 with Greater Turning (gains even more Turn Undead attempts through Night Sticks and swapping Air and Good Domain for Undeath and Charm via the Substitute Domain spell)
- Telepathy and Read Thoughts at will
- Radiance: Light spells cast at +1 spell level and offer twice the illumination
- Cloak of Shadows offer 40% concealment
- Immune to all diseases
- Has wings and limited flight capability with good maneuverability
- Pretty damn sexy thematically (glowing power sigil + cloak of darkness = cool)
Tricks:
1. Planar Bind a Skurid (CR 1/2 Native of the Plane of Shadow) into my service and cast Planar Bubble on it for free maximization and +10% quasireality on Shadow Evocation and Shadow Conjuration
2. Switch any current domain to the Spell Domain via Substitute Domain and use Greater Anyspell to replicate Draconic Polymorph and morph into anything with high Str and then persist it. The selected form, the +8 Str from the spell, and the Aeshkrau Power Word will allow for a good number of bonus spell slots. When 9th level spells are accessible, use Miracle to replicate and persist Bite of the Werebear for a +16 enchantment bonus to Str for even more bonus spells!
Concerns:
I'd like to retrain Precocious Apprentice into something else a little more useful. Legally, I can since the rules for retraining a feat only require that the choice for the substitute feat should be one that I could have legally made that the level that I acquired the feat to be substituted. However, I'm wondering what effect this will have on the rest of the build considering the fact that I used Precocious Apprentice to merit early entry into Rainbow Servant.
Anyway. Critiques? Constructive criticism, anyone?
Also, I'd like to lower my dependence on the Substitute Domain spell to gain access to other powers. I was wondering if you guys could suggest any Outsider that, thematically, would allow me access to the Sun (To quality for Radiant Servant of Pelor), Spell (Needed for Greater Anyspell to replicate Draconic Polymorph), Planning (For the free Extend Spell), and/or Undeath (for Extra Turning) domains? Sun and Planning are the domains that are a real must and essential for the build. Undeath and Anyspell would be nice but not quite as necessary. Really can't imagine anything besides a Solar. The Sun domain fits and I guess Planning is a good substitute for Law I suppose. Getting planning through Rainbow Servant would obviate the need to take Contemplative and allow me to get other class features (specifically, Turn Undead or Shadow Illusion) sooner.
