The Fever System is a Zero-exclusive feature that provides players with a new kind of game mechanic centered around more challenging maps and monsters, and greater rewards. This system is broken up into Fever maps (i.e. fields & dungeons), bosses, and random options.
Fever Fields & Fever Dungeons
Fever Fields & Dungeons are special maps that have stronger variations of certain monsters. These monsters drop Fever equipment, which have better equipment options. Also drops on these maps, which is important for various equipment crafting.
A Fever map entrance has a red portal.
Dynamic Field vs Fever Field
A Fever Field can also be a Dynamic Field because it requires killing X number of a certain monster to spawn a Boss. Sograt Desert Fever Field and Geffen Fever Field are examples of Fever Fields that are also Dynamic Fields.
Current Fever Fields & Dungeons
A Fever Boss is a Boss-type monster that drops equipment with Fever Options. These bosses may be on a Fever Map, like Dark Phreeoni, or may be on a Dynamic Map, like in the Clock Tower.
