Your control of the undead is nearly absolute.

Prerequisite(s): Command Undead.

Benefit: When you command undead, the DC of the Will save increases by half your tier, and intelligent undead get no additional saves beyond their first to resist your commands. Any attempts by non-mythic creatures to control undead you command automatically fail, and you gain a +4 bonus on Charisma checks to prevent mythic creatures from stealing control of your undead.
