| Players | Mob HP | Mob DMG | Ship HP | Rating |
|---|---|---|---|---|
| 1 (Solo) | 1.00× | 1.00× | 1.00× | Normal |
| 2 | 2.00× | 1.00× | 1.00× | Very Hard |
| 3 | 3.00× | 1.00× | 1.00× | Brutal |
| 4 | 4.00× | 1.00× | 1.00× | Brutal |
| 5 | 5.00× | 1.00× | 1.00× | Brutal |
| 6 | 6.00× | 1.00× | 1.00× | Brutal |
| 8 | 8.00× | 1.00× | 1.00× | Brutal |
| 10 | 10.00× | 1.00× | 1.00× | Brutal |
Solo row (grey) is your baseline. Values above 1.0× mean tougher than vanilla.

Windrose Co-op Scaling Guide
Windrose dedicated servers let you control how difficulty scales when players join your world. The Coop_MobStatsCorrectionModifier in WorldDescription.jsonadds a percentage of mob HP and posture for each player beyond the first. Understanding this before launch prevents the most common complaint on Windrose servers: "mobs are too easy with 2 players" or "impossible with 6."
Solo / Low Co-op
Scaling: 0.0
Flat difficulty. All players see identical mob HP regardless of group size. Best for large casual crews or events.
Balanced
Scaling: 0.5–0.8
Each extra player adds 50–80% mob HP. Groups of 2–4 stay challenged without becoming impossible for newer players.
Hardcore
Scaling: 1.0–1.5
Full scaling. Every extra player meaningfully increases mob HP. Requires coordination and good gear for large groups.
WorldDescription.json Co-op Parameters
| Parameter | Default | What it does |
|---|---|---|
| Coop_MobStatsCorrectionModifier | 1.0 | Scales mob HP and posture per extra player. 1.0 = +100% per player, 0.5 = +50%, 0.0 = no scaling |
| Coop_ShipStatsCorrectionModifier | 0.0 | Scales enemy ship HP per extra player. Default 0.0 — ships don't scale with group size |
| Coop_SharedQuestObjectives | true | All players in the world share quest progress and objectives |
| MobHealthMultiplier | 1.0 | Base mob HP before co-op scaling is applied |
| MobDamageMultiplier | 1.0 | Flat mob damage — does not scale with player count |
| ShipHealthMultiplier | 1.0 | Base enemy ship HP before co-op scaling is applied |
| ShipDamageMultiplier | 1.0 | Enemy ship cannon damage — flat, no co-op scaling |
