Minecraft Dungeons:Phantom

The Phantom is an hostile mob that appears at Night when a player dies in multiplayer.

Spawning
The phantom can only be summoned when a player dies in multiplayer. Unlike their default counterparts, the phantom is immune to all attacks and can only be stopped by reviving all defeated players and ending the night status.

Sometimes, in levels such as the Pumpkin Pastures, you can see their shadows flying around in circles around you.

Behavior
Just like their default counterparts, the phantom will swoop down on players, but will first start with one player then groups of them will swoop other players until they're killed, ending the night.
