Svirfneblin Figment Master
(Races of Faerun, page 169, DnD 3.0)
[General]
Your time underground has made you acutely aware of even slight differences in sound and vision in caves that have never seen the sun. Accordingly, your illusions are finely tuned and ultra-realistic.
Prerequisite
Deep gnome
Benefit
Your Illusion (figment) spells and spell-like abilities gain +1 spell power (+1 on save DCs and +1 bonus on checks to overcome spell resistance).
