You can weave your spells together with another caster, augmenting their mystic power.
Benefit: As a standard action, you can ready an action to plait one of your spells into that of a second spellcaster, weaving the mystic energies of the two spells together. When the allied spellcaster casts a spell, you take your readied action to cast your spell in response. Rather than have its normal affect, your spell grants your allied spellcaster a +2 enhancement bonus to his caster level for the spell that triggered your readied action. The spell you use to plait with your ally’s must be within 2 levels of the spell cast by your ally, and cannot be a 0-level spell (which lacks the power to plait).
