Channeling Energy from multiple classes

[I'm Hiding In Your Closet]

For instance, if somone's a multiclass Cleric / Hex Channeler Witch, do the dice stack? What about the uses per diem?

Sneak Attack dice stack, so that would be pretty analogous, but the rules I see appear silent.

Disregard this provably wrong answer of mine. Thanks, I grok do u!

No.

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.

So track separately your uses per day and number of dice.

Note that some PrCs DO stack like holy vindicator

Dang, note to self: do your homework before you offer an opinion!

So one wouldn't get more dice per Channel, but one would get rather a lot of uses, none of that "overlap" shysterism?

Pretty much.

One of my personal favourite channeling builds would be a Cleric 1 / Ravener Hunter Inquisitor X, which with the Channeling Scourge feat would give you full scaling negative energy channel for the purposes that matter. Ravener Hunter would let you pick up the Channel revelation, giving you almost full scaling progression for positive energy. (still capping at 10d6 if I remember the scaling right at level 20). Just make sure that your cleric domain powers are not reliant on level scaling.

[Melkiador]

A spirit guide life oracle can actually take channel twice with the life spirit. It's a lot of channels. More than you can reasonably use in one adventuring day.

Well, I'm aiming for a Mystic Theurge/"True Necromancer"; any advice for that?

Not 100% sure what you'd want by "True Necromancer", but if the idea is that you want to channel to command undead and to heal the living, you could potentially do some combination of a Spirit Guide Oracle that grabs the Life Spirit (for Channel positive at level 4, as Melkiador commented above), and with the Bones mystery you can pick up Command Undead with 3+CHA uses as a Revelation, together with getting Animate Dead as a bonus spell known at level 6. Just make sure to have a good flavor justification, as these might be seen as not being entirely compatible with one another. (A spirit guide cannot bond with a spirit that is incompatible with her alignment, ethos, or mystery (GM’s discretion).)

If limited Theurgy is your goal, and you don't want stuff like Equipment Trick: Sunrod for early access, I'd suggest picking up Planar Heritage (Shabti) and making your own mini-theurge list with spells known from the Psychic list. That way you get full Oracle casting progression, as well as essentially selective 8th level spell access from the Psychic list.
