Upon casting this spell, the caster temporarily gains 3 + (1 per caster level) ranks in any desired skill. The chosen skill must be one that the caster already has ranks in, and the entire bonus may only be applied to one skill. Skill ranks apply equally to both class and cross-class skills. The caster gains no additional bonuses for multiple applications of this spell.
