Tenacious Magic
( Player's Guide to Faerûn, p. 45)[General]
You can use the Shadow Weave to make your spells harder for Weave users to dispel.
Prerequisite
Shadow Weave Magic (PG) ,
Benefit
Your spells resist dispelling attempts made by Weave users. All creatures employing spells or spell-like abilities are considered Weave users unless they possess the Shadow Weave Magic feat. When a Weave user makes a dispel check to dispel one of your spells (including using dispel magic to counterspell a spell you are casting), the DC is 15 + your caster level. This benefi t does not extend to spells you cast from the schools of evocation or transmutation.
