Omninomicon Entry
Vicious, hellish beings of perdition that brutally slaughter any non-hellish creature nearby. They use face-melting fire attacks to incinerate their victims.

Behavior
Upon seeing the player, a demon will start moving towards them(if the player is less than 11 blocks away) or will throw a fireball at them(if the player is further than 11 blocks away). If brought into the Overworld, demons will avoid water, as water will harm them. s will often gather around large lava lakes, and will swim in lava to regain health.
