Revenants are undead creatures bent on pursuing revenge against individuals who wronged them in their previous lives. As undead creatures, they have no survival instinct per se; instead, they’re driven by compulsions, in this case the compulsion to avenge themselves.
Now, you might argue, hey, you can’t get revenge if your enemy (or someone else) destroys you. And revenants have high Wisdom, high enough to understand the truth of this—and above-average Intelligence, high enough to understand the fact of it. So you might think a seriously wounded revenant would break off fighting and retreat—that is, unless it was getting too close to its one-year deadline.
But you can’t destroy a revenant. Its Regeneration feature restores 10 hp every round unless it’s taken fire or radiant damage; only if the damage that finally reduces its body to 0 hp is fire or radiant damage will the body it inhabits be destroyed. And even when the body is destroyed, the soul returns 24 hours later in a different body.
The only way to keep this from happening is to banish the revenant’s soul to its appropriate afterlife while it’s disembodied, using a wish spell. Only the most powerful wizards and sorcerers—veritable masters of the world—will have access to that. What kind of favor do you think you’d have to do for one of them to get him or her to cast a wish spell on your behalf? (The Monster Manual doesn’t mention this possibility, but I think you could probably also stop a revenant by bringing it back to life with a true resurrection spell. But this is also a 9th-level spell; instead of wheedling a favor out of Saruman, you’ve got to get it from the pope.) (more…)
