Welcome all forum users.
I am playing a combination of wizard/archivist/mystic theurge
All spells seems to work right with an exception of blade barrier for which dc is always 19 (dosesn't matter if i change any ability or add spell focus feat)
I've tried this spell with pure cleric and everything was fine there.
Earlier i had a problem with adding 8,9 level spells to archivist book, but replacing prc_data files rectified this.
What can i do about blade barrier?
Edit: Let me add i use 3.5 version and i'm playing single player
