Found what was nagging me about loot drops and why they seemed below what was set. So did some reconfiguring as follows:
At all levels there's a 1/3 chance to drop all equipped ammo (unchanged) if creature drops something. Bosses always drop stuff (the demonweb sub-bosses are because bril hates you, sorry).
CR 15 and below: Random items are varied and desirable. So 1/3 of the time they drop something it'll be from equipped items (either only that or in combination with other items from tables). Half of that time it'll be two equipped items if they have that equipped.
CR 16 to CR 32: Creature specific items more desirable. 60% of the time include equipped item, 25% of that 2 (if they have 2).
CR 33 and up: How many IA tridents do I need? Always from equipped if available, 10% of the time 2.
Bosses of all levels drop 1 to 3 items (unchanged) as well as guaranteed table rolls and double gold. Also a pony. Of course this can get frustrating with Lolth when you get the hair tie instead of a ring or a ring and armor or a ring and armor and knife and pony...
Unique is in there somewhere (generally a creature will have other treasure as well as that--didn't change that).
Amazon bosses are the only ones that won't drop every time (there's a lot of them). Most other creatures drop 20% of the time (remember law of large numbers, sometimes you kill 5 creatures to get a drop, sometimes 3, sometimes 10). I'm willing to negotiate on that (tuna is higher, don't remember what precisely), but I can see endgame going to 30 or 40 in sparsely populated areas or things with tons of items to pick from like glimmers (robe, kamas, boots, I forget what else).
Joran and I originally envisioned loot not doing that much for you and it just being bytes, so there should be enough that you have to choose what to haul away. Then came epic levels and inventory expanders and ...
So pitch any ideas/complaints/death threats you have. I'm pretty sure you don't want to know how bad the chances of creature specific items used to be before I looked at it
