Frenzy Field

A Frenzy Field, sometimes referred to as a Fever Field (Korean: 피버 필드, literally "Fever Field") is a special type of map location present in Zero and Transcendence. This map system does not exist in Renewal.

A Fever Field will spawn Champion monsters after a certain number of normal monsters are defeated, and will spawn Boss monsters after a certain number of Champion monsters are defeated. These monsters can drop equipment with special random options not available from the drops of regular monsters.

Transcendence mentions 10 normal monsters specifically to spawn a Champion.

A portal leading to an active Fever Field map will have a different colour.
