FAQ
Channel Energy: If I have this ability from more than one class, do they stack?
No—unless an ability specifically says it stacks with similar abilities (such as an assassin's sneak attack), or adds in some way based on the character's total class levels (such as improved uncanny dodge), the abilities don't stack and you have to use them separately. Therefore, cleric channeling doesn't stack with paladin channeling, necromancer channeling, oracle of life channeling, and so on.
按这个说法，帕帕丁和牧师的引导是分开算的。按你的例子来说既是5级帕帕丁就是3d6，消耗圣疗。1级牧师就是1d6，消耗牧师的引导次数。
