After the death of the Goddess Etain, other Gods sought to take over Teos by creating monsters.

A monster's name will be displayed in a certain color to represent its level. A monster with increased stats for its level is known as a boss.

Many monsters live in clans.

When a monster is killed it has a random chance to drop; gold, items and/or equipment for the character that did the most damage. They will also give experience based on the level difference between them.
