Shadow Trickster

(Tome of Battle: The Book of Nine Swords, page 32, DnD 3.5)

[General]

Your mastery of the Shadow Hand discipline lets you augment your illusion spells with the stuff of shadow.

Prerequisite

Caster level 1st, one Shadow Hand strike

Benefit

While you are in a Shadow Hand stance, the save DC for any illusion spell you cast increases by 2. You also gain a +2 bonus on damage rolls when making a sneak attack, a sudden strike (see the ninja class description, page 8 of Complete Adventurer), or when you flank your target
