A monster (aka mob) is an in-game, non-player entity that you, as a player, can fight.

Killing monsters is the major aspect of Atlantica PvE (player versus environment). Monsters come in groups, aka formations, and will attack you between 1 and up to 3 groups at a time, depending on your location.

You kill monsters in Atlantica for quests, loot and to gain experience.
