Channeling

When a paladin channels positive energy, all evil foes within a twenty foot radius burst suffer radiant energy damage equal to X, where X is the product of Y and Z. Y is the sum of the paladin's Charisma and Wisdom modifiers. Z is the paladin's total divine levels (includes any clerical levels, plus paladin levels).

For example, at overall character level 8, Whiteheart has Charisma 17 (a +3 modifier) and Wisdom 13 (a +1 modifier); therefore Y is 4. Z equals 8. Thus, when Whiteheart at this level channels positive energy, the damage inflicted to evil creatures within its area of effect is 32 points.

A paladin may channel divine positive energy as often as every other combat round.
