Minecraft Dungeons:Shulker

The Shulker is a hostile mob found in the Echoing Void. It appears similar to its Minecraft counterpart. It is unknown how Shulkers will behave in the DLC.

Behavior
Shulkers, like their base counterpart, will shoot shulker bullets at players, which deal damage. Also unlike their base counterpart, their bullets are capable of activating special contraptions, which are yet to be seen.

Shulker Bullet
A shulker bullet is a guided projectile that is shot from shulkers, and they follow the targeted entity along the X, Y, or Z axis and leave trails of white particles. A shulker bullet that hits a mob or player deals damage and affects them with Levitation for ten seconds.

The shulker's projectiles also have entity data that control its movement.

The bullet can be destroyed by hitting it with any item, shooting it with an arrow, or blocking it with a shield. It explodes upon contact with a block. The explosion does not destroy any blocks and does not damage nearby mobs or players.
