RobbyPants brought up something I hadn't realized about the BAB, so I decided to go cloistered cleric at level 1 to fill out the fractional BAB for CloiClrc 1/ Wizard 3/ Duskblade 2/ Spellsword 1/ Abjurant Champ 5. I'll tell you about my build so far, and I'd totally appreciate guidance about where to go after level 2!
I'm second level so far with Boccob as my deity. I traded the free cloistered Knowledge Domain for Knowledge Devotion, got back Knowledge Domain to get all Knowledge skills as class skills, and got the Planning Domain for free Extend Spell. For my lvl 1 feat, I took Persist Spell.
Now that it's second level, I can Persist 1 lvl 1 Cleric or Wizard spell with Illumian Naenhoon.
I chose to go with Abrupt Jaunt Conjurer Specialist. I'm trapped on an island, so there will be no shops or people to buy scrolls from for a long while.
My spells are:
expeditious retreat, swift
wall of smoke
I'm really proud of my build so far, and I'd totally appreciate input on where you think I should go from here based on the above!
