You can channel negative energy to animate undead.
Prerequisite: Cha 25, Undead Mastery, ability to rebuke or command undead.
Benefit: You can use a rebuke or command undead attempt to animate corpses within range of your rebuke or command attempt. You animate a total number of HD of undead equal to the number of undead that would be commanded by your result (though you can't animate more undead than there are available corpses within range). You can't animate more undead with any single attempt than the maximum number you can command (including any undead already under your command). These undead are automatically under your command, though your normal limit of commanded undead still applies.
If the corpses are relatively fresh, the animated undead are zombies. Otherwise, they are skeletons.
