Core Fever Rules
🔥
Random Options
Every Fever equipment drop can roll random stat options themed to that map. Fever rolls can include powerful positive effects and controlled drawback options, creating valuable but imperfect gear chase items.
💎
Rupes Nigra Materials
Fever monsters can drop Rupes Nigra materials. Harder maps, elite monsters, and Fever MVPs are the best source of higher-tier materials.
⚠️
GvG / WoE Restriction
Fever set bonuses and special combo effects are disabled on maps flagged as GvG, WoE, Castle, or Guild War.
Fever Random Option Structure
How Fever Rolls Work
Fever equipment is designed to roll positive bonuses and may also roll drawback options. Drawbacks are not negative drop chances; they are normal item options with negative stat effects. This keeps the system compatible with Ragnarok-style item scripting while making perfect rolls more valuable.

Mythic Fever Combos
Optional Prestige Layer
MVP cards should not gate normal Fever progression. They are better reserved for a future Mythic layer: extremely rare, prestigious, and stronger than the normal Powerful combos. This keeps Fever progression playable while preserving the excitement of true MVP-card chase items.
| Map | Mythic Card | Suggested Mythic Upgrade |
|---|---|---|
| Forest | Moonlight Flower Card | Stronger movement, stronger Blind-on-dodge, higher ranged scaling. |
| Desert | Phreeoni Card | Massive HIT and stronger DEF ignore against evasive/boss targets. |
| Glast Heim | Doppelganger Card | Higher ASPD and stronger Soul Strike / Spectral Echo procs. |
| Magma | Kiel-D-01 Card | True after-cast-delay caster route. |
| Abyss Lake | Drake Card | Stronger boss/Large DEF penetration and weapon freedom. |

Implementation Notes
- Drawback options should be implemented as separate random-option IDs with negative effects in the option script.
- Store option values as positive numbers and apply the negative sign inside the script where needed.
- Fever MVP equipment should not always be perfect. The best items should come from strong positive rolls with no drawback or with a harmless drawback for the player's build.
- GvG / WoE disable logic should be handled in the equip script or central Fever bonus controller.
