You’ve got a huge ancient red dragon that has flipped out. It’s on the rampage. You must stop it or the devastation will be severe and widespread. You have a couple dozen volunteers willing to make the ultimate sacrifice to save hundreds or even thousands, but to what avail? What the hell can you do to defeat an ancient red dragon?
Actually, there is a way, even with low-level warriors. But it’ll take some coordination and three necessary components:
You need quite a few volunteers, both the ones who will be in front-line battle and others willing to distract and pre-occupy the dragon (probably by being slaughtered indiscriminately).
You need a new or modified spell. I don’t know if there is already a spell that specifically does something like what I’m about to describe floating around out there in one of the dozens of supplements, but it doesn’t seem like a big leap to make it work in the D&D schools of magic (probably wouldn’t rate more powerful than a fourth or fifth level spell tops). This spell is cast on an item and creates a delayed teleportation effect. Should the owner of that item ever die, the item will immediately pass into the hands of another person (determined at the time of the spell casting).
You need a Vorpal sword. (Of course you need a Vorpal sword! What were you thinking? This is a frickin’ ancient red wyrm we’re talking about here.)
Okay, here’s the game plan. The item transference spell is pre-cast on a number of people, setting the transference up like dominoes: when one goes down, the item is passed along to the next person, and the next, and the next.
You’ve got any number of volunteers engaging with the dragon, probably with zero efficacy. They’re dying left and right, but they set it up so that your first warrior, armed with the Vorpal blade, can get in a hit.
If he rolls a 20 it’s all over. The most ancient, most powerful red dragon poses little threat when relieved of its head.
Unfortunately, you know that even with a Vorpal sword there’s a 95% chance the blade does little more than tickle the dragon. And your warrior is likely only going to get the one shot, immediately after which he will be reduced to a pile of ash.
But with your object transference spell active on the Vorpal blade, it immediately materializes in the hands of the next warrior, who takes her one shot – and who then, with anything but a roll of 20, gets free cremation service. The sword is like a relay-race baton, passing along to the next wielder and the next. Eventually (odds are good that it’ll be within 20 shots), one fighter is going to land a hit that has the full effect of Vorpal power, and the ancient red dragon will never have to shave again.
By that time you might have lost 50 brave souls (the sword wielders plus all the other volunteers ineffectively blasting away to keep the dragon occupied), but to take down a monster that can lay waste to armies and level whole cities, this seems a rational price to pay.
So there you have it. Go ahead, start trying to poke holes in this plan. Or feel free to propose your own. I’ll be especially impressed if you’ve got one that doesn’t require a Vorpal sword…
