I beleive every channel energy abiliity depends on CHA for uses per day and DC. Every one excep for the warpriest's
Channel Energy (Su):
Starting at 4th level, a warpriest can release a wave of energy by channeling the power of his faith through his holy (or unholy) symbol. This energy can be used to deal or heal damage, depending on the type of energy channeled and the creatures targeted. Using this ability is a standard action that expends two uses of his fervor ability and doesn't provoke an attack of opportunity. The warpriest must present a holy (or unholy) symbol to use this ability.
A good warpriest (or one who worships a good deity) channels positive energy and can choose to heal living creatures or to deal damage to undead creatures. An evil cleric (or one who worships an evil deity) channels negative energy and can choose to deal damage to living creatures or heal undead creatures. A neutral cleric who worships a neutral deity (or one who is not devoted to a particular deity) channels positive energy if he chose to spontaneously cast cure spells or negative energy if he chose to spontaneously cast inflict spells.
Channeling energy causes a burst that affects all creatures of one type (either undead or living) in a 30-foot radius centered on the warpriest. The amount of damage dealt or healed is equal to the amount listed in the fervor ability. Creatures that take damage from channeled energy must succeed at a Will saving throw to halve the damage. The save DC is 10 + 1/2 the warpriest's level + the warpriest's Wisdom modifier. Creatures healed by channeled energy cannot exceed their maximum hit point total—all excess healing is lost. A warpriest can choose whether or not to include himself in this effect.
The Warpriest channels energy using her WIS for the DC.
So what happens with the command undead feat? Would it apply differnt to a Warpriest's channel energy? Is it 10 + 1/2Warpriest level +WIS?
Command Undead:
As a standard action, you can use one of your uses of channel negative energy to enslave undead within 30 feet. Undead receive a Will save to negate the effect. The DC for this Will save is equal to 10 + 1/2 your cleric level + your Charisma modifier. Undead that fail their saves fall under your control, obeying your commands to the best of their ability, as if under the effects of control undead. Intelligent undead receive a new saving throw each day to resist your command. You can control any number of undead, so long as their total Hit Dice do not exceed your cleric level. If you use channel energy in this way, it has no other effect (it does not heal or harm nearby creatures). If an undead creature is under the control of another creature, you must make an opposed Charisma check whenever your orders conflict.
Or is it just crap for the warpriest, as it would be the only thing they do with CHA?
