Also, how much would people charge for an item that provides a +1 to +5 competence bonus to one save? Note: that's competence, not resistance. This would be ideal for, say, fighters with a +10 Will save at 15th level, with a +5 resistance bonus already figured in. Or a wizard with a +10 Fort save. Would (bonus squared) x 1000 gp suffice?
(bonus squared) x 1500 I'd say. Skirting the standard stacking rules (there are things that add compentence bonuses to saves, but the're not
too common) can be powerful. I might also be tempted to simply limit the ability to rings alone and let it slide by at 1000x. (I sometimes don't allow certian bonuses to be added to wonderous items, requiring forge ring instead, but that's just me)
As far as the original question, there are a lot of options. You could come up with prices for these via formulas or by compairing them to other items in the DMG, but I won't bother to provide any, as this is fully at the descression of your DM.
Circlet of free will: this is a simple silver circlet engraved with very fine flowing engravings running along it in a fluid manner. It provided SR 18 vs. hold spells.
Pendant of inner fire: This is comprised of a faceted emrald that glows with a faint green flame from within on a simple string. Every day the wearer can act normaly for the first 4 rounds when they would be under the effects of a
Hold Person or
Hold Monster spell. The spell is supressed for these rounds, after this limit is up it again takes effect. During this time the wearer receves a +2 moral bonus to all attack and damage rolls.
Ioun Stone (pale lavender disk): this functions exactily like a standard (ellipsoid) pale lavender ioun stone, only it only functions against
hold person, absorbing the spell (as long as it's under 4th level) with a readied action.
