Minecraft Dungeons:Enchanter

Enchanters are illagers that enchant other hostile mobs making them stronger and more dangerous.

Appearance
Enchanters wear a wine-colored robe, similar to the evoker's, a wine turban, a cape and carries a book in which it uses it to enchant nearby mobs and possess villagers.

Behavior
Enchanters enchant other hostile mobs greatly improving their stats such as health, attack power and size. They shoot their magical beam to one mob at a time. If a player gets too close to one, it will hit them with it's book, dealing a bit of damage. Both mobs involved in the enchantment must be alive for the enchantment to be sustained; if the Enchanter is killed, the enchantment ends and the mob returns to normal.

Trivia

 * Some Enchanter's sounds have distorted villager sounds.
