Ring of Anti-Disjunction

[Tormsskull]

Ring of Anti-Disjunction
If the wearer of this ring is targeted by a Mage's Disjunction spell, the spell has no effect upon them and is reflected back upon the caster.

I don't know of anyone who actually makes use of this spell, but in a world where it exists, high-level characters are sure to ward themself against it. Thus, this ring. It takes up a useful spot (ring) and is extremely limited in scope, so I am thinking the price would be quite low (maybe 25,000). Any suggestions on price/level requirements/spell requirements to create?

Spell Turning seems the most obvious choice for a prerequisite spell.

Perhaps a specially-prepared Ring of Counterspells? The standard version wouldn't work, but one made to hold higher-level spells could provide you with protection from 3 Disjunctions (by which time, you should've fled or trashed the spellcaster).

i agree with MrNexx-- 25,000 for 3 charges (absorbing)
100,000 for 3 charges (reflecting, single target(no aoe))
