So often I've read at other sites (like DF) where people don't like dragons being the toughest monsters in the game because, in their words:
"After all, it is called Dungeons & DRAGONS. You should be able to fight dragons regularly."
I never understood that thinking. As a DM, I always make dragons very powerful. They get 12 sided HD, for one thing. They get to use their breath weapon as often as they like, but only once every 3 rds. (that doesn't mean I DO have them use it that often, only that they CAN do so). And so on and so forth. It's the damned titular monster, for god's sake! But even so, you can always have dragons appear regularly. I've often wondered if the people who say that don't realize that dragons have age categories.
Sure, if you send a Great Wyrm Red Dragon against a 3rd level party, there is no need to roll. Just tell the players: "The dragon killed you all instantly. Roll up new characters." It would be abusive to do so. But a lower level party like that, why can't they fight a hatchling or perhaps a very young dragon? I've always done it that way. As the party goes up in levels, they get to fight older and tougher dragons. And yes, I am working my way to the debate itself. Hang in there!

So yeah, dragons are probably the toughest monsters overall in the game. I hate when people at DF start the HD/thaco comparisons and "game it out" that way, because if you use dragons correctly, they are goddamned deadly no matter what level the party. Only a foolish DM would have a dragon stand toe-to-toe and trade blows with a huge high level party.
But demons (and devils)...those bastards are tough too! They're tough for several reasons. One, they have very high magic resistance. Two, they're immune to quite a few forms of damage. Three, they get lots of attacks. And four, worst of all (along with MR), is their ability to gate in other demons.
You have, for example, a party of 5 fighting a marilith. It's got 70% MR and gets 7 attacks per round, many of which are with magical weapons (I love using swords of wounding, swords of sharpness, and vorpal swords
![Twisted Evil :twisted:](./images/smilies/icon_twisted.gif)
Balors are tough too. 70% MR, -8AC, can gate in 1-4 greater or 1 true demons once per hour, with 100% chance of success. So in the first round it gates in 1-4 babau, with an average of 2 being summoned. They each, in turn, have a 40% chance of gating in 1-6 cambions or 1 extra babau. Of the two, one will most likely succeed, so that means on the third round the PCs are facing:
1 balor
2 babau
3 cambions
All have high MR. That's 1 demon for each PC (in the aforementioned party of 5). If the demons get lucky, it could be as many as:
1 balor
4 babau
24 cambions
Or imagine if the balor gates in a vrock, which then gates in a nalfeshnee, which then gates in another vrock, which then gates in another nalfeshnee, etc.
So in a matter of a few rounds you could be facing an army of demons, all of whom have an AC of -7 to -9, high MR, spells, immunities, multiple attacks each, deadly special attacks, and the ability to gate in other demons.
I don't honestly know which is tougher. I've had parties wiped out by dragons in a few rounds, and I've had parties swarmed and destroyed by demons or devils in a few rounds.
What do the rest of you think?
