Difficulty notes#
- Freshly constructed ordinary wild creature; no paragon conversion, control/summon scaling, equipped/stat offsets, spell effects or special runtime transformations. Endless Journey expansion branches assumed. Missing skill/resistance assignments use zero. Numeric interval endpoints may not co-occur.
- Unresolved monster ability or group widens the estimate to the ability-score cap.
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.
Difficulty-based loot budget#
For eligible wild creatures that request treasure, the difficulty system replaces ordinary gold and equipment rolls with one budget. A difficulty estimate crossing a tier boundary shows every possible tier. The eligibility and source-call conditions above still apply.
| Difficulty | Gold budget | Guaranteed equipment | Extra item chance | Properties | Intensity |
|---|---|---|---|---|---|
| D41–60 | 100–220 | 0 | 55% | 2–3 | 25–55 |
| D61–80 | 250–550 | 1 | 35% | 3–4 | 45–75 |
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 × Filthy 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 × 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 × Gems loot theme | Requests a matching optional supplement theme within the shared difficulty budget. | No condition in extracted rule |
| PackLootItem(new PowerCrystal()) | Requests a newly created themed item: Power Crystal. Ordinary equipment is rerolled at death; supply and map limits apply. | No condition in extracted rule |
| PackLootItem(new BlackthornWelcomeBook()) | Requests a newly created themed item: Blackthorn Welcome Book. Ordinary equipment is rerolled at death; supply and map limits apply. | if (Utility.RandomDouble() < 0.02) |
Scripted drops and item transfers#
These operations occur in the named methods. They can describe encounter rewards, service transactions or other item transfers; they are not an unconditional corpse-drop list.
| Operation | Method | Interpretation and conditions |
|---|---|---|
| c.DropItem(DawnsMusicGear.RandomCommon) | OnDeath | Places a scripted item into a container. Read the source conditions and method context. if (Utility.RandomDouble() < 0.05) if (!IsParagon) if (Utility.RandomDouble() < 0.75) |
| c.DropItem(DawnsMusicGear.RandomUncommon) | OnDeath | Places a scripted item into a container. Read the source conditions and method context. if (Utility.RandomDouble() < 0.05) if (!IsParagon) else |
