The campaign has been running a while and will continue to run for a while to come... i'm just rerolling because I got bored of my Warlock.
Contemplative just needs ranks in Knowledge Religion to enter and I don't really want to lose spell levels anywhere if at all possible. Archivist 11 is for the fun stunning ability =p not worth it?
Well if you really want to use Archivist 11/, go right ahead. Since it's a long campaign, the cloistered cleric dip likely won't be worth it. The Contemplative dip is a good idea -- I was thinking of the Divine Oracle prereqs when I recommended against it.
Unfortunately, taking 11 levels of Archivist makes my Spellguard suggestion obsolete. IIRC they get their share spells ability at level 4. It might still be worth it, though, since it shares some prereqs with Spelldancer and gives bonus metamagic.
Archivist 11/Contemplative 1/Spelldancer 1/Spellguard of Silverymoon 1
The problem I have with this is that it doesn't get Share until ECL 17.
It may be worth considering going
Archivist 11/Contemplative 1/Spelldancer 2 (if you wear light armor)
or
Archivist 11/Spelldancer 1/Divine Oracle 2 (if you wear heavy armor, but it's more feat intensive)
either of these would get you Evasion.
Needing Archivist 11 seems a bit restrictive, but it's not like you'll be hurting for power. Spelldancer is more abusable than (already banned) DMM for Persistent Spell. I hope your DM doesn't mind you persisting all of your ultimate power spells (I'd guess that's exactly what he was trying to prevent by banning DMM).
