Help with a Mystic Theurge Lich Build

[Kulmara]

I've been playing a build in Lich, but this playthrough was mostly to get a better understanding of a few things not mentioned in the wiki. Such as what the Lich powers are, and what is Staunton Vayne's class. Also what about the roles of an undead team. I wanted to build an ultimate Lich, so I wanted to focus on being a Scythe wielding maniac. But now that I got there I am using the Scythe far less than I thought I would.

I realized that I should rebuild the character, however a lot of decisions I made in regards to my companions (picked Wenduag instead of the far superior Lann, had Daerien and Ember learn Inflict spells, trained Ember to brew Inflict potions) were built on the notion that I would be a front line fighter. So I decided to start the campaign from scratch with the intention of leveling my character as a Mystic Theurge, using Arcane magic for offence and Divine magic for defense and support.

Only problem is that I don't know which Divine class to choose. My divine class has to be one that uses Charisma--but not Wisdom--as a spell casting modifier, so that I can get the Selective Channel feat after I unlock my first Mythic rank. I can't choose Paladin because of alignment restrictions and it would take too long just to reach the 1st level magic tier. I can't choose Oracle because the only revelation in the Bones mystery that would work with multi-classing is Resist Life, and that's useless to a Dhampire. I only want enough levels in a Divine class to unlock Harm (level 6 Divine spell).

Does anyone have any ideas? Are any of the Wisdom divine class Archtypes that use Charisma instead, while still focusing on casting?

Also, a side ponder, does anyone know what happens if you have multiple Channel abilities with the same energy type? Do they stack, do you get different abilities with different number of times you can use them? Knowing this would help me reduce my options.

The only divine archetype I know of that does that is Feyspeaker for the druid, but that probably isn't what you're looking for, since druid doesn't get Harm as a spell.

My advice would be, if you're using arcane for the offense and divine for defense and support. You don't need to worry about pumping in the stats for divine too high because defense and support spell effectiveness is not really dependent on the ability score (they don't really require saves). You only need enough to cast the highest-level of spells you would get for divine (10 + spell level), and you'll probably end up equipping a headband of mental perfection anyway.

If you absolutely want to use Charisma for both, Oracle is your best bet. It's not mandatory to take Bones as a mystery if you're going Lich. Though Armor of Bones is a pretty good revelation early game since you probably won't be wearing armor.

As for channeling, in the rules for tabletop, they don't stack, but you get separate pools of channel energy uses.

Actually, I want to use the Headband of Mental Perfection, and give Charisma headbands to my undead allies (since they use it in place of constitution). I'm now considering doing Witch instead of Wizard. I have also decided to go with Oracle after all, but use Waves as my Mystery since a lot of Necromancy spells deal Cold damage. Also, Witch has a lot more options when it comes to offensive Necromancy spells. Here's hoping for the best.
