Yea I think I will let a swarm out.
One of the gold pieces they grab actually bites back. ^^
Then the swarm comes out. At the worst it just eats up one or two aoo spells, at the best it kills some mirror images and a little CON dmg, though I really doubt that anyone wont make the save.
And it gives the dragon enough time to come out somewhere else and position himself without giving the group a free shot round.
The only weapon that actually works would be 1d3 torch or the flaming hammer of the barbarian. Though only the 1d6 fire dmg applies.
That should stop them from looting before the dragon is dead.
-----
A little planning ahead: The elfs wait at the exit of the cave which leads into a pit. From there only a stairway leads 40ft up. Thats where the 5 Lv11 elves are waiting.
Group:
1.Archer type - he would be dead already, but he got mauled into unconciousness and taken hostage by our group. Later freed by the elves, who never actually showed themself to the group, but they know they are there. Thats why his stats are lower than before - he got looted. ^^
2. Assasin: She hates humans, has a human bane dagger and favorite enemy humans. Her spells might come in handy if she decides to go into melee combat.
3. Cleric of Hexxtor. Basically the same ord. champion as our cleric. He will grow thanks to righteous might and buff the elves up. His ace is his only Lv5 spell: "Death throes"
4. Wizzard, nothing special, mass enchant, dom. person, and dmg spells.
5. Warblade - Originally it was a really strange fight/ X/ X mix so I just rewrote it to a warblade. She has an unholy sword that deals nice extra damage, but except for 1 or 2 manneuvers she has mainly conters to bug the melees.
Plan: If the group stays in the cave to rest they send a summoned animal in to disturb them.
Maybe they place something small in the entrance hall as an alert signal when they are coming.
The wizzard prepares a wall of dispel agic at the entrance while the clerics starts to buff.
The two melees will be positioned a little down the stairs and fight our melees head on. While the other 3 stay on top and attack from the distance.
