Minecraft Dungeons:Vex

Vexes are flying hostile mobs found in Minecraft Dungeons.

Spawning
For it to spawn, the evoker has to be within the range of the player and it will spawn as one of the evoker's spells.

Behavior
Unlike the base game, the vex will attack you like any normal enemy, not being able to go through walls. There is no limit as to how much vexes there are following the player.
