I just wanted to make a few observations about the value of items and the amount of treasure from encounters in the test material.
I noticed most weapons and armour in the test material are valued in gold. I strongly feel that at the beginning of their careers, adventurers would be using copper and some silver. I think basic adventuring gear should be priced at a few copper pieces, basic weapons and armour at a few silver. Perhaps give a PC 50 silver to start off with. I would simply suggesting dividing the cost of weapons by 10. The price of general equipment seems ok to me.
When a PC starts with 100gp to spend, finding 10cp on some kobolds is pretty meaningless.
In the Cave of Chaos adventure, some monsters dropped copper, some silver, which I think is fine, but there was some electrum and some gold and even platinum in the adept's chambers. I would imagine gold would start to appear perhaps level 4 or 5, or from the hoard of a special monster. I think there is too big a disparity between the level of treasure from the monsters at the start of the adventure, to those at the end.
So for example, perhaps the kobolds at the start of the adventure have around 10sp, but the medusa at the end might have items worth 250sp.
So the bottom line: Adventurers should be using (and finding) copper and silver coins at low levels.
