Demon Skulls

Demon Skulls help you fight with various passives, if you feed them well.

Their main source of EXP:
 * from Orb of the Banished (can be bought from the guy in the Forgotten Cemetery)


 * from items like equipments (any quality)
 * from being equipped with a hero and the hero kills monsters (recommended)

After equipping them to their own slot on your characters, you can tap on them, and with dragging their 'food' to their face, you feed them. In this menu, you also can see if you have any point by their level up which you can use to ugrade one of their passives.
