The loot is incredibly random. I screwed up during my first trip through the tutorial dungeon, and had to reload. First time through, there were "rain" scrolls in barrels or crates near the fire floor, there were a couple of crafting books, nearly 200 gold (a couple of piles of 90-some gold), a fireball scroll in a crate near the poison cloud, etc. Second time through, there was no fireball scroll in anything near the poison cloud, which led me to repeating the content a third time, whereupon I found no rain scrolls, no recipe books, around 50 gold total, and no equipment, unless you want to count a paper knife that had less than half the damage of my starting knife, which gave out from durability when opening the door the tutorial suggested bashing through.
Actually, this sounds like you've hit the "
world not resetting on quickload" bug.
The items you mention [rain / fireball scrolls] are hard set as items (i.e. hand placed as objects) and are
not from the RNG loot tables. Loot tables are chests / containers & certain mobs only atm.
So, yeah: you're complaining about a bug, not a feature.
