Fever Fields

⚔ Fever System

The Fever System transforms selected fields and dungeons into high-stakes hunting zones. Fever maps contain stronger monster variants, random-option equipment, Rupes Nigra materials, themed set bonuses, special boss encounters, and item combo effects. Fever entrances are marked by a red portal.

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.

Guaranteed: 1 random option

Bonus positive: 50%

Drawback: 50%

Elite Fever Monster

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.

System Reference

Fever Maps at a Glance

Map	Set	Core Identity	Normal Combo Route
Payon Forest	Forest	HP sustain, Brute/Plant hunting, Poison pressure	Bathory / Nine Tail + Eggyra
Sograt Desert	Sand	DEF, Sleep, Fire resistance, accuracy	Sandman / Goblin Mask / Andre
Glast Heim	Shadow	Undead/Demon hunting, SP economy, Shadow resistance	Agav / Waste Stove + Bison Horn
Magma Dungeon	Magma	Fire resistance, kill sustain, hybrid fire pressure	Salamander / Imp / Magmaring + Flame Lord
Abyss Lake	Dragonbone	Dragon hunting, boss pressure, Large targets	Yellow Acidus + Ulle's Hat / Nidhogg + Bone Head

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.
