Essence of Undeath

A more powerful form of undead summoning, this spell animates a dead corpse into an undead warrior. Unlike the minor, temporary zombies created by "Summon Undead Champion", this spell binds a kansen into a dead body, creating a powerful Tainted revenant which serves the caster to the best of its ability. The revenant will last indefinitely (until destroyed), and the Taint infusing its body prevents it from decaying further. It cannot speak, but can understand and obey any verbal command. It will serve the maho-tsukai who summoned it until it is physically destroyed.
