This is the status-effect reference. Each entry: what it is, where it comes from, what it does, and how to clear it. For the underlying systems, Immortal Realm Maladies and Mortal Shock.
Maladies (Chronic Conditions)
Maladies are organized as chains — multi-stage progressions where untreated stages worsen on a per-chain timer. Some chains have a "flat-feeling" entry stage (The Shakes, Mire Lung) that's actually stage 1 of a longer chain. Escalation only ticks while you're online.
| Chain | Stages | Escalation (between stages) |
|---|---|---|
| Battle Fatigue | Battle Fatigue → Shell Shock → Lingering Trauma → Internal Bleeding | 2h / 4h / 8h |
| Combat Aches | The Aches → Stiff Joints → Fragile Bones → Broken Limb | 2h / 4h / 8h |
| Crafting Strain | Repetitive Strain → Numb Hands → Trembling Grip | 3h / 6h |
| Crowd Sickness | Crowd Fever → City Plague → Wasting Sickness | 4h / 8h |
| Dungeon Sickness | Dungeon Cough → Cave Sickness → Deep Rot | 3h / 6h |
| Miner Strain | The Shakes → Numb Arms → Weak Grip → Miner's Collapse | 3h / 5h / 10h |
| Prison | Institutionalized → Cabin Fever → Blood Fever → Prison Madness | 1h / 2h / 4h |
| Swamp Sickness | Mire Lung → Swamp Fever → Bad Blood → Blood Poisoning | 3h / 6h / 10h |
Call Stones is also a real malady (a CallStones standalone class, not a chain stage). It progresses through internal stages within a single class rather than across the chain registry.
The Prison chain is the fastest-escalating: leaving an Institutionalized stage untreated for an hour escalates you to Cabin Fever; another two hours and you're at Blood Fever; another four hours and Prison Madness lands. The shortest of the chains in human terms.
For full malady mechanics, Immortal Realm Maladies. The exact list of maladies is part of what you discover in-game; the table above covers the registered chains.

Civic Justice Flags
| Flag | Cause | Effect | How to Clear |
|---|---|---|---|
| Murderer (red) | Killing innocents | Free-attack target | Standard UO murder-count decay; long-term |
| Criminal (gray) | Looting blue corpses, attacking blues in guarded zones | Temporary attack-vulnerability | Time decay (60-min CrimeTracker window) |
| Token fine on crime detection | CrimeTracker recording | Time Tokens deducted per CrimeTracker.cs:163-176: Snooping 0 / Theft 1 / BenefitCriminal 1 / AssaultNpc 2 / AssaultPlayer 3 / MurderNpc 3 / MurderPlayer 5 |
Avoid future crimes; the deduction is immediate and capped at current balance |
| Active Player Writ | Another player filed against you (5,000g + a Public Writ Deed) | Hunters can claim and pursue you for 120 minutes | 15-min Surrender to the Warden, hunter fails, expiry, Velvet Hand scrub/redirect, or kill the hunter |
| Crown protection window | Recently resolved writ on you | New writs blocked against you | Wait the 45-minute protection window |
| Imprisoned | Successful writ claim or surrender | Locked in Warden's prison (Trammel) for 15 min | Sentence served; or a Ledger-crafted Bail Contract / Parole Deed delivered by another player |
Crown Writs target NPCs, not players — there is no "active Crown Writ on you" state. The Ledger's Officialized Player Writ path keeps Branch=Player but adds Crown branding; the writ is still a Player Writ from the system's perspective.

Common Mistakes
- Ignoring early-stage maladies. They progress to harder-stage versions. Treat early.
- Stacking maladies. Multiple maladies compound. Don't ignore symptoms.
- Letting Mortal Shock cap. You become unable to fight effectively. Get Last Rites at 8+.
- Missing the murderer count timer. Long-term murderer status persists; track it.
- Not bonding pets. Bonding is the only way to resurrect a dead pet.
