Many monsters inhabit the world of Agon of all sizes and difficulties. Monsters like goblins, undead, hivekin and more inhabit some areas around starter cities. Kill these monsters using your melee weapons, archery, or magic to train your skills and stats and to increase your wealth.
When you kill a monster they will leave a grave behind, just like players. This grave can be opened by using the F key. You can loot the items on the grave by either single clicking each item or by conventional drag-and-drop methods.
Beware that other players can take the loot from the grave of the monster that you killed, though that will turn them rogue for a short period of time.
