I have a Cleric/Paladin and, at the next level, my paladin should be able to use Channel Energy. On the paladin's page, it says that
A paladin uses her level as her effective cleric level when channeling positive energy.
However, since I can already use this feature as a Cleric, would the levels stack and the only differences be the uses/days and the attribute used, or would I use the paladin's channel energy as another feature entirely?
