This question came up in our game this weekend: the party faced and killed a called glabrezu demon (as distinct from summoned, as outlined on pages 209-210 of the Core Rulebook); glabrezu are "treasure: standard" which given the CR and the party's level amounts to 17,500gp worth of loot, but there was no treasure evident.
Presuming the demon had been called to the site via planar ally and bound there for only a few days, is it supposed to bring its treasure with it? Gaining an outsider's temporary service via planar ally does require payment, but in this case the payment was non-monetary and involved some unfortunate and now-deceased NPCs.
It seems really odd that creatures like this should carry all their wealth with them do do short term contract work, but Pathfinder doesn't appear to make distinctions between "in lair" treasure and other amounts of loot, as AD&D 1e did.
Thoughts?
Also, bear in mind that wealth by level is a guideline. Your GM doesn't have to follow that guideline if he chooses otherwise.
I am the GM for this game. I don't mind them having some more loot at this point, this was just a situation where it seemed odd there should be any.
The notion of disassociating treasure with encounter locations -- if you kill a monster you earn "X" amount of treasure, but the monster or location in question doesn't necessarily have any connection to it -- provides some flexibility but will take some getting used to: "kill the monster, take its treasure" becomes "kill the monster, find a bunch of unguarded loot [or an absurdly rich kobold, or excessively generous employer] miles away at some later date."
If it brought its wealth with it, then it should have used that wealth for the fight with the party (for instance, it could have had a +2 weapon or a belt of giant strength, etc). Otherwise, its wealth would remain behind somewhere.
Many published adventures place wealth in terms of various valuable items existing within the dungeon that aren't necessarily directly tied to the creatures faced there. Such as books in a private library, bottles of wine in a private bar, or expensive statues and jewelry.
It shouldn't be entirely disassociated, however. It should always make sense for the location and the creatures encountered.
