Considering an Spellthief/Sorcr/Wizard/UltimateMagus/UnseenSeer Blend - Any thoughts?

[Tonal Architect]

My last character died, so I'm playing with a few different ideas right now. The latest one is:

01 SpellThief 01
02 Sorcerer 01
03 Wizard 01 *Take Practiced spellcaster to sorcerer
04 W 02
05 W 03
06 UM 01 - W04 S01 (05)
07 UM 02 - W05 S02 (06)
08 UM 03 - W06 S03 (07)
09 UM 04 - W07 S03 (07)
10 UM 05 - W08 S04 (08)
11 UM 06 - W09 S05 (09)
12 UM 07 - W10 S05 (09)
13 UM 08 - W11 S07 (10)
14 UM 09 - W12 S08 (11)
15 UM 10 - W13 S09 (12)
16 UnSeen Seer 01 (W14)
17 USS 02 (W15) -> Advanced Learning, Silent Spell for free
18 ArchMage 01 (W16) [or whatever]
19 AM 02 (W17)
20 AM 03 (W18) (S12) (ST1) (Arcane Spell Power +4) = CL 35

Build will take advantage of Spellthief's Master Spellthief arcane class level combination, and presumably Persisted Hunter's Eye, for a whopping CL 35 and 12d6 sneak attack, in case I can sell that to my DM. (advice on how to diplomatically achieve this is appreciated).

Any advice on what this build? Any feat advice? Is there something else I should consider for further optimization?

Probably it would be better to cover the spontaneous side of the UM with Beguiler (INT synergy).

Are you planning to play this character from level 1 on?

Skip the sorcerer. you take the Trickster Variant of Spellthief, they have similar to Bard casting.

Trickster Spellthief 2/Wizard 3 will let you into Ultimate Magus easily at 5th.

I'd recommend a PRC that gives you higher spontaneous casting faster, Nar Demonbinder or Sublime Chord come to mind as soon as you can get them, then continue with Ultimate Magus.

Trickster Spellthief 2/Wizard 3/Ultimate Magus 6/Nar Demonbinder 1/Ultimate Magus 4 etc.

[Tonal Architect]

The trickster variant doesn't appeal to me, I'd rather stick with a full caster from the beginning.

The Beguiler suggestion, while at first not being met with enthusiasm, grew on me. It won me over the moment I went through the sorcerer's spell known x level. The moment I realized a sorcerer will only know a single spell at level 4, I placed my character in line to sign him up for Beguiler lessons. Those guys have a lot of variety to them.

I'm now wondering whether the character should go Human or Illumian. Illumian, while not obviously so, could provide a +4 total attribute bonus, given the way their sigils provide modifier bonuses rather than attribute ones. The human extra feat is attractive, though.

Well, final build so far, assuming a human character:

01 Beguiler 01 -> Extend Spell, Invisible Spell
02 SpellThief 01
03 Wizard 01 -> Practiced Spellcaster: Beguiler
04 W 02
05 W 03
06 UM 01 - W04 B01 (05) -> Master Spellthief
07 UM 02 - W05 B02 (06)
08 UM 03 - W06 B03 (07)
09 UM 04 - W07 B03 (07) -> ?
10 UM 05 - W08 B04 (08) - UM Bonus Feat ->
11 UM 06 - W09 B05 (09)
12 UM 07 - W10 B05 (09) -> ?
13 UnSeen Seer 01 (W11)
14 USS 02 (W12) -> Advanced Learning, Silent Spell for free
15 UM 08 - W13 B06 (10) - > ?
16 UM 09 - W14 B07 (11) - UM Bonus Feat ->
17 UM 10 - W15 B08 (12)
18 [whatever] Arch-Mage 01 - W16 -> ?
19 AM 02 W17
20 AM 03 W18

By the time the character has taken the second USS level, he'll have reached CL 25, dealing a grand total of 10d6 sneak attack damage, casting two levels below a pure wizard, and casting second level beguiler spells for support.

Not too shabby, I'd say.

Alternately, you can take Sublime Chord, which allows you to pull the same stupid CL tricks. An odd build option, but a viable one (especially if you have Heartfire Fanner for easy access to bardic music).

[Malachei]

For Ultimate Magus, Illumian is a very good choice, because the Krau sigil adds +2 to caster level, which helps you to further improve UM casting progression in addition to Practiced Spellcaster.

If you decide to use persistent then illumians just outpace anything.

while int buffing can not go above 40-50,
str buffing can reach 100-120 str score.

combining that illumians can make their bonus spells per day trrascend from str.... that's +15 9ths per day... ouch!!

Wow. Could you provide further details on how to reach that much strength and intelligence? Sorry if that sounds newbish.

Also, I have a question: On those spells that have a duration descriptor of "x rounds/level", does level, in this question, refer to Class level, or Caster level?

caster level.

[hex0]

caster level.

And caster level is so easily exploited. Master Spellthief, Nar Demonbinder, Sublime Chord, Chameleon, Practiced Spellcaster, Ultimate Magus, Krau Symbol...

There are certain things that are capped at caster level, but it saves you from having to take spell penetration and makes your spells much harder to dispel. If you are feat starved, Master Spellthief is often better than Practiced Spellcaster as well.
