11th level Boggard Oracle of Bones, Cha 16
add new revelation "Undead Servitude"
Undead Servitude (Su): You gain Command Undead as a bonus feat. You can channel negative energy a number of times per day equal to 3 + your Charisma modifier, but only to use Command Undead. You can take other feats to add to this ability, such as Improved Channeling, but not feats that alter this ability, such as Alignment Channel.
Using foul powers of necromancy, you can command undead creatures, making them into your servants.
Prerequisites: Channel negative energy class feature.
Benefit: 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.
by my calculation this should be
6 uses (3+Cha)
HD limit 11 (Oracle 11)
DC 18 (10 + 1/2level + Cha)
Reported values are
6 uses (OK)
HD 18 (wrong)
DC 11 (wrong)
Undead Servitude (Su)
[Paizo Inc. - Advanced Player's Guide, p.46]
You can channel negative energy 6 per day, but only to use Command Undead. You can command up to 18 hit dice of undead. The will save DC of this ability is 11.
Pathfinder core ruleset
Indicative of where the problem may lie:
Feat Improved Channel: "Add 2 to the DC of saving throws made to resist the effects of your channel energy ability."
But for Undead Servitude, it adds 2 to the HD limit, and nothing to the DC.
So if we are seeing HD reports DC, and DC reports Cleric Level, we are nearly there
values shown are same in inside-PCGen Preview, and in Exported PDF
Values for HD and save DC were reversed.
