Channel energy and multiclass

[Drimoran]

Hi. I had some questions about channel energy I hoped you could help me answer.

Cavalier - Order of the Star - Calling:

At 2nd level, the cavalier can make a short prayer as a standard action, filling him with confidence in his abilities. At any point in the next minute, he can receive a competence bonus on an ability check, attack roll, saving throw, or skill check equal to his Charisma modifier. He must declare that he is using this bonus before the roll is made. He can use this ability up to four times per day, once for each type of check or roll. In addition, the cavalier adds 1/2 his cavalier level to any levels of paladin or cleric he might possess for the purposes of determining the effects of channel energy or lay on hands.

Does the channel energy bonus (text in bold) apply always or just for the next minute after using this ability?

Do other classes with "channel energy as a cleric of X level" benefit from this?

Warpriests do not cannel energy as a cleric of X level but have as many dice as her fervor ability. Would they benefit from this?

Envoy of Balance - Endowment - Spiritual Equilibrium:

The envoy of balance's class levels count as cleric levels for determining the effects of her channel energy ability. If she has the spontaneous casting class feature, she is no longer restricted by the choice made at 1st level to convert prepared spells into cure or inflict spells. Each time the envoy of balance converts a spell, she can choose to convert it into a cure spell or an inflict spell.

Do other classes with "channel energy as a cleric of X level" benefit from this?

Warpriests do not cannel energy as a cleric of X level but have as many dice as her fervor ability. Would they benefit from this?

Thanks in advance

always applies. As written only paladin's or clerics. So rulewise, just those, Easy houserule to make if houserules are an option.

again, as written it's cleric, and cleric levels don't stack with say an oracle's effective cleric level for channeling. Again, easy houserule if that's an option.

This is unfortunate because they don't write material to work well with future material, nor update older material to work with new material. BUT it has been there stance that you follow the text and that only the explicitly called out classes get the benefits.

It always applies, not just while using that ability.

Do other classes with "channel energy as a cleric of X level" benefit from this?
Typically no. Anything that specifically says it stacks will stack, like the cavalier ability. If it doesn't mention stacking, then it doesn't stack.

Warpriests do not channel energy as a cleric of X level but have as many dice as her fervor ability. Would they benefit from this?
No.

[Envoy of Balance ability]

Do other classes with "channel energy as a cleric of X level" benefit from this?
This is much more case-specific, but probably not.

Warpriests do not cannel energy as a cleric of X level but have as many dice as her fervor ability. Would they benefit from this?
No.

Furthermore, to take Spiritual Equilibrium, you need Versitile Channeler (feat), which requires you to be a True Neutral necromancer (for turn/control) or cleric (of a True Neutral deity), so no other class currently qualifies to take that feature of Envoy.
