You can cast this spell only if it is the first action you take on your turn. In a burst of shadowy feathers, you turn into a Tiny blurred shape reminiscent of a black raven until the beginning of your next turn.
If you succeed at a ranged touch attack, you burn your handprint onto the flesh of a creature, dealing 1d6 points of acid damage and when it is within 60 feet of you, cursing it with a -2 penalty to AC against your attacks and on saving throws to resist any spell you cast or spell-like ability you use. Additionally, each day the target remains cursed, more and more of its flesh becomes covered in reptilian scales.
Touched shield grants wielder SR 10 + caster level against spells if it can be interposed between the wielder and the spell effect (not against AOE spells such as fireball, but does provide +5 bonus to Reflex saving throws against such spells.)
You gain a deflection bonus to AC vs. attacks from creatures with a neutral component to their alignment, you may banish such creatures, and you automatically dispel any one enchantment spell cast by such a creature.
