Our long awaited battle against a bbeg (Gargantuan Black Dragon) is going to be anticlimatic due to the fact that two of the players have cancelled at the last minute. The last few sessions have been leading up to this encounter and the PCs are expecting to face the dragon tonight. Just short of cancelling the session or throwing a one-off at the party, what can I do? Do you have any suggestions on how I can keep this from being a TPK?

The battle looks like this:

Hook "When my immense form comes into view, those who would call themselves my enemies shudder in fear as I swoop down to tear them apart."

Crush (Ex) This special attack allows Mavarothix to land on opponents as a standard action, using its whole body to crush them. Crush attacks are effective only against opponents of size Medium or smaller (though it can attempt normal overrun or grapple attacks against larger opponents). A crush attack affects as many creatures as can fit under the dragon's body. Creatures in the affected area must succeed on a Reflex save (DC 34) or be pinned, automatically taking bludgeoning damage during the next round unless the dragon moves off them. If the dragon chooses to maintain the pin, treat it as a normal grapple attack. Pinned opponents take damage from the crush each round if they don't escape.

Tail Sweep (Ex) This special attack allows Mavarothix to sweep with its tail as a standard action. The sweep affects a half-circle with a radius of 30 feet, extending from an intersection on the edge of the dragon's space in any direction. Creatures within the swept area are affected if they size Small or smaller. Affected creatures can attempt Reflex saves to take half damage (DC 34).

Breath Weapon (Su) Mavarothix's breath weapon is a line of acid 120 feet long that does 22d4 points of acid damage. Using a breath weapon is a standard action. Once a dragon breathes, it can't breathe again until 1d4 rounds later. A blast from a breath weapon always starts at any intersection adjacent to the dragon and extends in a direction of the dragon's choice. If the breath weapon deals damage, creatures caught in the area can attempt Reflex saves to take half damage (DC 34).

Frightful Presence (Ex) Mavarothix can unsettle foes with his mere presence. The ability takes effect automatically whenever Mavarothix attacks, charges, or flies overhead. Creatures within a radius of 330 feet are subject to the effect if they have fewer than 34 HD. A potentially affected creature that succeeds on a Will save (DC 31) remains immune to that dragon's frightful presence for 24 hours. On a failure, creatures with 4 or less HD become panicked for 4d6 rounds and those with 5 or more HD become shaken for 4d6 rounds. Dragons ignore the frightful presence of other dragons.

Water Breathing (Ex) A black dragon can breathe underwater indefinitely and can freely use its breath weapon, spells, and other abilities while submerged.

Corrupt Water (Sp) Once per day Mavarothix can stagnate 10 cubic feet of water, making it become still, foul, and unable to support animal life. The ability spoils liquids containing water. Magic items (such as potions) and items in a creature's possession must succeed on a Will save (DC 31) or become fouled. This ability is the equivalent of a 1st-level spell with range 330 ft.

Mavarorhix is out for the evening. Instead, they meet its offspring, Thysdree, the half-dragon twelve headed hydra sorcerer 4 (CR 15).
 

Do the players know how old the Dragon is? If not you could bring it down an age category or two. A very old black dragon seems a better challenge. On the other hand, if you have the Gargantuan Black Dragon mini it would be a shame not to use it...

You could have two of the players run 2 characters.

You could postpone the battle for a session as the players run into a LBEG (perhaps a Kobold Cleric of Tiamat and his followers, or one of the dragon's Half-Dragon children).

You could give the players some useful magic items- A Dragonbane sword, some dragon-slaying arrows, some kind of acid-resistance item...
 

5 14th level characters vs a CR 20 critter? Nasty. 3 14th level characters vs a CR 20 critter? Comprising two '5th characters' and a multiclassed main spellcaster? TPK. How about them encountering into a Simulacrum instead? And a weak one at that. They'll only know once it disolves into snow. Can your characters actually hit AC39?
 

How about the ol' Velociraptor vs. T-Rex trick? The PCs aren't the only people after this dragon. They either get allies, or they're shadowed by the second group of bad guys, and during the climactic battle, those bad guys jump in and turn the tide. The party will have a 3-way fight on their hands.
 

The dragon isn't as old as his size indicates. He's actually only an old black dragon who, due to the favor of Tiamat, has a permanent Righteous Might effect (at Tiamat's caster level, so it's basically not dispellable). I'd say the effect is powerful enough to raise an old black dragon's CR to 17 (given that he gets all those size G dragon bennies), but not so powerful that he overwhelms the party. The disadvantage is that you'll have to re-stat the dragon, but if you might have to if you don't want a TPK.

Another option is to assume the dragon has enemies, and that some CR 16 enemy attacked him that very day and consumed 25% to 50% of his resources (in the dragon's case, HP and spells) before defeating that enemy. The PC's might be able to finish him off.

Given the build-up, I think it's quite fair to run those missing players' characters as NPC's, perhaps as the CR 16 threat that consumed the dragon's resources. But I guess the morality of THAT is the subject of another thread...
 

Have the bard cast a few illusions to look older, and have him visit a seedy tavern. Eventually a sufficiently powerful party of adventurers will come by looking for work. Hire them to do the job :) .

More seriously, if you can't just find a way to stall until the next planned session, recruiting high-level NPCs (bards aren't great force, but they're great force multipliers) and spending disproportionate amounts of your budget on expendable magic items may well be useful.
 

I can see three ECL 14 PCs taking down a gargantuan CR 20 dragon (and no, I'm not talking about Pun-Pun ;) ), since I've seen five ECL 13 PCs and an ECL 14 NPC take down a colossal CR 25 Iron Kingdoms dragon (considerably nastier than the conventional kind).

Those PCs, however, included a dwarf rifleman/officer who was an expert at party buffing and could do upwards of 200 damage on a crit (with a wide crit range), a dwarf rifleman (who could do even more than the rifleman/officer and at similar ranges), and an elven holy slayer type who could use magic device to activate an archeotech cannon for similar ranged damage, albeit less consistently, a monk with a PrC that allowed him to fly, and a druid. Between the three shooters, they tore the dragon to shreds in a couple of rounds and probably could have handled it without the rest of the party; certainly any one of them would have had at least a slim chance of soloing a CR 20 dragon.

A (multiclassed) bard, a (multiclassed! :confused: ) cleric and a straight monk? Do they have *any* source of ranged damage? I suppose the cleric can handle acid resistance and fear resistance, but what offense does he have against a dragon?

I'm not seeing much chance for them to beat a CR 14 dragon, much less a CR 20 one. They'd need some truly astonishing tactics, and the dragon would have to behave in a fairly stupid fashion, for it not to be a TPK.

Completely agree with this one. And its not just about the danger of the party facing the dragon. This is an event that your players have been building for a while, its just not "right" to have half the party miss out on it. Players cancel, it happens, but don't let that spoil what might be one fo the hallmark fights of your game.

Have them fight something else, they've been building for this long, they can wait a little longer:)
