Esoteric Abjuration

(General)
A carefully selected set of geodes causes the defenses you create with your spells to offer even better protection.
 

Benefit

When you cast an abjuration spell using geodes as an esoteric material component, you can grant a single target of that spell a +1 Competence Bonus on its Fortitude, Reflex, or Will saving throws for the duration of the spell. The spell must have a duration measured in rounds or minutes, and a creature can benefit from no more than one bonus from this feat at a time. When you gain geodes' greater component effect with an abjuration spell, treat your caster level as an additional 1 higher for determining the duration.
