I'm trying to minimize the cleric (and related PrCs) levels in a build while still getting enough Caster Level to avoid being dispelled by, say, a lucky _chain dispel_ cast by an Inquisitor.

I've already considered several items:

 - The Ring of Enduring Arcana (CM) gives a +4 CL for resisting to dispel only.
 - The Orange Prism Ioun Stone gives a +1 CL
 - The Prayer Bead of Karma gives a +4 CL
 - The MIC has an Ankh that makes me spend spell slots to get a +4 CL on the next spell
 - SpC has a magic tattoo that gives another +1 CL

The Practiced Spellcaster feat helps, but I'm trying to get less cleric levels in order to gain fighter feats, so (while still advantageous) it is a last resort.


**Is there anything else I could do to become undispellable (save for antimagic or disjunctions)?**
