Is Naberius and Zceryll abuse okay with you? Are Bloodlines? What about flaws?
Here's the E6 build skeleton of the Void Caster Build (I'll convert it later):
Jurando (former name), CN or TN or LE (I have very little idea what alignment Naberius is) Human Binder 1/Wizard, Cleric, or Sha'ir (fluff Sha'ir as having your familiar power your spells with the power of the void) 1/Anima Mage 1/Major Bloodline 1/Anima Mage 2/Major Bloodline 1/Anima Mage 1/Major Bloodline 1
Feats:
1: Practiced Binder
Flaw: Magical Training
Flaw: Precocious Apprentice
Human Bonus Feat: Extend Spell
3: Dark Speech (Lets you speak the language of raw evil, allowing you to do cool effects at the cost of some ability damage)
6: Dark Whispers (Lets you terrify people in a thirty foot radius of you by speaking to them in the Dark Speech, at the cost of a point of CHA damage (which Naberius heals the next round))
E1: Persistent Spell
E2: Uncanny Forethought
E3: Expel Vestige
"No, you don't get it. We don't worship Naberius; we are Naberius." -A Member of the Cult of the Dog
Jurando is a member of the Cult of the Dog, a group of spellcasters whose mental abilities scores have been regenerated so many times by Naberius that they have mentally become him. They have no intention of bringing Naberius to the material world; he'd rather stay in the safety and power of the void while building a power-base on the material plane via the Cult. Thus, the Cult is relatively harmless, provided that you don't make any deals with them.
Skeletonier build for a Druid that transforms into Beholders:
Human Heritage Lesser Aasimar Druid 2/Major Bloodline 1/Druid 1/Chameleon 2/Major Bloodline 1/Druid X/Major Bloodline 1/Druid X
Take Assume Supernatural Ability (Eye Rays) and Aberrant Wildshape, and go to town (Use the floating Chameleon bonus feat to snag the abilities of other aberrations when necessary or to craft).
I also have an Archivist/Elemental Archon available.
The Chameleon build is a lesser D'hin'ni that gets its first Chameleon level as its third level (not including bloodlines) and Spellthief as its first level. The Nar-Priest seems too cheesy for this game.
So, which build would you guys like for me to flesh out more? Keep in mind that all of these builds were intended for E6, and I can change them if they're too cheesy.
