Random Treasure
What you find besides the fixed treasure the story puts in place: random magic items and potions in containers, and the spoils of fights. Each place rolls its share the first time you come, from your playthrough's seed, and keeps it.
In a place's containers
- Magic items: none 10% of the time, one 40%, two 50%; a place with 3 or more containers gets one more 50% of the time.
- Potions: none 25% of the time, one 50%, two 25%. Each is a healing potion for your tier 60% of the time, else any potion of the place's rarity.
Fights
Story fights you win leave coins by each foe's Challenge Rating and one find (a healing potion, a gem or a spell scroll). Beasts, plants, oozes and mindless creatures carry no coins. Strahd's visits, road fights and arrests leave only their own spoils.

Party level by region
Each region's containers roll for this party level (a place can set its own).
How the rolls work
Random magic item placement (story/treasure.gd, ADR 0012). The party's level in each region (from the region design docs) decides the rarities, following the 2024 DMG's treasure guidance: tier 1 (levels 1-4) mostly common and uncommon items, tier 2 (levels 5-10) mostly uncommon and rare with the odd very rare one. A location can name its own level with "treasure_level". No common items (owner, 2026-10-08: early commons become uncommon, later ones rarer): the DMG's common share goes to uncommon.
A roll picks a rarity, then a theme (arcana, armaments, implements, relics) evenly, then an item in it by weight. A theme whose pool at that rarity weighs less than theme_full_weight gets a share in proportion, so a theme with one or two items doesn't hand them out in a quarter of all rolls (owner, 2026-10-12).
