4 Seas Jug is an artefact which decreases the army size of the opposing troops by 5%. This artefact has a requirement of level 20, and requires 60 mana each time it is used. This item can be obtained from treasure items (see infobox).
Though in the description of the item on War of Legends it says it decreases the opposing army by 5%, this actually decreases the enemy's military Strength by 5%.
The animation shown when using this in battle depicts a mushroom cloud. Oddly, mushroom clouds, which are generally formed from nuclear explosions, were not seen until the twentieth century.
