Magic Portal

Magic Portals (魔法陣) are yellow magic circles containing trapped monsters, found in the areas of The World. When a player approaches the portal, it disappears, summoning one or more monsters to attack. However, sometimes, treasure chests appear in place of monsters. These chests can either be trapped or normal.
