Loot eligibility#
Ordinary treasure is conditional on encounter eligibility
One shared difficulty gold/equipment budget can apply when the requested treasure theme is reached and all runtime eligibility checks pass. Conditions on the source loot calls still apply.
Requested gem, potion and scroll supplements use their separate theme/AI/body checks and one shared optional-supplement roll.
This evaluates definite source exclusions and requested themes. It does not inspect live ownership, summoned status, corpse contents or world spawns.
- Creature is not deleted or a player.
- Creature is not summoned, controlled or bonded.
- Creature has no recorded owners.
- NoKillAwards, IsInvulnerable and Blessed must all be false at generation time.
- Ordinary loot is generated only once; existing generated gold and ordinary equipment consume that budget.
Loot and special drops#
Source calls describe requested themes, conditions and inventory. Ordinary equipment/gold are reconciled through DifficultyLoot; these calls are not additive guaranteed payouts. Runtime dispatch and conditional special rewards still apply.
Drop rules#
| Loot request | Interpretation | Condition |
|---|---|---|
| 1 × Rich loot theme | Requests ordinary treasure within one shared difficulty budget; repeated pack requests do not multiply the payout. | No condition in extracted rule |
| 1 × Average loot theme | Requests ordinary treasure within one shared difficulty budget; repeated pack requests do not multiply the payout. | No condition in extracted rule |
| 1 × Low Scrolls loot theme | Requests a matching optional supplement theme within the shared difficulty budget. | No condition in extracted rule |
| 1 × Potions loot theme | Requests a matching optional supplement theme within the shared difficulty budget. | No condition in extracted rule |
| PackLootItem(new SulfurousAsh(Utility.RandomMinMax(3, 5))) | Requests a newly created themed item: Sulfurous Ash. Ordinary equipment is rerolled at death; supply and map limits apply. | No condition in extracted rule |

Summoning references#
This creature type is referenced by a summoning spell. That does not mean every instance is a summon; control and summon state change loot and progression eligibility.
Notes#
- Source type availability does not establish a live spawn, location or current world count.
- Taming, summoned status, paragon conversion and other runtime effects can change displayed stats or progression eligibility.
