Description: You use your undersranding to help or hinder the magic affecting you

Prerequisites: WIS 13, Void Use, Way of the Phoenix

Required for: No Illusions

You may spend a Void Point as a free action to help or hinder any spell that specifically targets you. The effective caster level of the spell is increased or decreased by one. If the spell's caster level is reduced to zero, the spell is canceled without effect.

Special

You may gain this technique up to five times. Each time it is gained you may spend an additional Void Point and thus increase or decrease the caster's level an additional time.
