Zenako-san --
Your hostage, the one remaining noble salamander in the citadel, is perfectly willing to ransom himself and his workers by leading you to what treasures remain here. This noble salamander is the metalsmith, an armorer and weaponer of some skill, and also seems less "nasty" than the other salamanders had been.
Anyway, by chamber/possessors...
From the two sentries by the gong, a bronze gong worth perhaps 10 gp, one set of desmodu "knucklebones" worth perhaps 5 gp, plus 6 flasks of frostfire:
Frostfire: a desmodu invention, sort of the opposite of alchemists' fire, a sticky adhesive substance which drains away heat upon exposure to air or moisture (i.e. it works underwater as well) worth 40 gp each. Grenadelike weapon, range increment 10', does d6 of cold damage on a direct hit. On the following round, a target that suffered a direct hit takes another d6 of cold damage. The target can use a full-round action to scrape off or wash away the frostfire, with a Reflex save at DC 15 to succeed. Dousing with at least a quart of an alcoholic or acidic solution (such as wine or vinegar) automatically removes it.
In various boiling mud pools (which would definitely burn characters unprotected from fire, probably about 10d6 worth), used as beds by the noble salamanders (four different locations), the salamander hostages scoop out a variety of loot for you, all in coins and gems.
In the main hall, where there were 4 noble salamanders lounging when your party so rudely invaded, you find that each of the four had a +3 longspear (normal sized for a human) -- according to the smith, those were the only magical weapons in the hands of those other than the leader and his efreeti slave -- other than the one he had just finished enchanting. So there are 5 +3 longspears. There are also a total of 25 masterwork longspears (worth it for their quality of manufacture, the smith does good worth) and about 60 normal javelins.
Nearby, the smith indicates that the huge red-hot boulders are actually a "permanent image" which the visiting efreet had created for privacy -- they could make them actually hot by putting a wall of fire within them, but vs the salamanders it was mostly just for visual privacy. Anyway, he walks through the boulders (you can do the same) and reports that there is no loot there (which you confirm).
There are a bunch of copper pots and plates and such in the kitchen, pretty low value, not worth taking probably. There are stores of animal and monster meat and other utensils in a nearby chamber as well. (Leaving these behind - Zenako)
In the area that the smith says belonged to the leader's efreeti, whose name was Zubenel, there is a brass and silver hookah worth about 35 gp, it weighs 5 lbs.
The leader, whose name was Helkitrin, was a wizard as well. He evidently took his spellbook with him, as well as some magical accoutrements -- but he did leave some loot behind, which the smith pulls out of a steam vent: another pile of coins and gems.
From the smith's own quarters, he retrieves the following loot: 22 platinum bars (1 lb each) worth 500 gp each (or less, needs to be worked into coinage)
Finally, in a storeroom in the lower level -- lots of pig iron and bronze ingots -- perhaps you'll give those to the desmodu, or allow the salamanders to keep them? (Going to leave and "gift" these to the locals - Zenako)
Not worth that much unprocessed...plus the following more portable wealth:
48 silver bars (1 lb each) worth 5 gp each (or less, needs to be worked into coinage)
5 flasks of frostfire
3 desmodu breathing masks, about half-charged each
2 thunderstones (per PHB)
4 smokesticks (per PHB)
1 tanglefoot bag (per PHB)
3 potions of Cure Light Wounds (desmodu)
And that covers it! -- Ernie III / DrakaraGM
