Cleric Domain - Focus or Fortitude

(Originally found on The Chamber of Mazarbul)

Domain: Focus OR Fortitude
When you pick your spells at the beginning of a Full Heal Up, you can choose any Daily Cleric spell twice, gaining two uses of that spell.
Invocation of Focus/Fortitude: Once during this battle you can allow an ally to make a Recharge Roll immediately after using a Recharge power. If they fail they can still attempt to Recharge the power after the battle normally. OR you can let an ally make a Normal Save immediately after using a once per battle power, and if they make the save they can use that power again.
Champion Feat: Reduce the power's Recharge result by 5 (so a Recharge 16+ power becomes Recharge 11+) for the bonus Recharge roll. Regaining a once per battle power becomes an Easy Save.
Epic Feat: You can affect 2 allies with this Invocation during this battle.
