Minecraft Dungeons:Phantom

The Phantom is a 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. Also, they easily spawn when you are in a bad spot, but you can prevent them from attacking by healing whenever the countdown starts to happen. This is easy whenever you either have a lot of souls and you can heal using a soul amulet, or whenever you have anything else that can heal you that you were saving especially for this. But, this might not always work...

Behavior
Unlike their default counterparts, The Phantom swoop to player vertically instead of horizontally, but will first start with one player then groups of them will swoop other players until all players are killed, or until the night ends due to all killed players being revived. The first bite deals 8% of the player's HP, 10% for the 2nd bite, 12% for the 3rd, and so on and the damage keeps increasing over time.

Trivia

 * The attack and flying behavior of phantoms in Dungeons is similar various species of hawks in reality instead of the original game, which used the Ender dragon's behavior.
 * The phantom is the first and only mob that is immune to all attacks.
