Your channeled energy grants your allies elemental resistance.
Prerequisite: Channel energy
Benefit: Any creature healed by a use of your channel energy ability gains resistance to an element of your choice. The resistance is equal to your Wisdom bonus (minimum 1), and lasts for one round for each die of healing dealt by your channel energy. You must choose a single element to grant resistance against each time you channel energy, you cannot grant different targets resistance to different forms of energy.
