One-starred bosses are bosses that players must defeat to complete one star quests. They are not as tough as Three-Starred Bosses, but still worth defeating.

One Star bosses can either be part of small Lairs, or one of two mini-bosses in Dungeons.

Defeating One-Star bosses in Uber Worlds (Uber 1 - Uber 5) will give players Shadow Key Fragments upon opening the chest they drop. Higher Uber Worlds will drop more fragments when defeating them.

Each biome has its own One-Star Bosses.
