Jar of Souls

Functioning similarly to the Happiest Mask, the Jar of Souls spawns a ghost at the location of all enemies onscreen, who will immediately begin attacking other enemies for you. After 15 seconds, all of the ghosts will disappear, like the ones spawned by Happiest Mask.

This item is most useful in large crowds, especially the crowds that spawn upon activating a portal. Doing so will cause all enemies to spawn a ghost on the player's side, and start attacking the crowds that spawned them. Even more useful is the fact that enemies will only attack the players, not the ghosts, allowing the ghosts to attack fairly freely. The best tactical position to use this item is by cliffs full of enemies, as the enemies will stop at the cliff and allow their ghosts to easily attack them.
