Evoker

An evoker is a hostile mob, and is one of the two "Illagers", the other being the vindicator.

Natural Generation
Evokers spawn inside naturally generated woodland mansions in groups of 1, alongside vindicators and other hostile mobs.

Drops
Evokers will always drop 1 totem of undying, as well as 0–1 emeralds.

Behavior
The evoker will attack players and villagers.

When not in the middle of summoning an attack, the evoker will attempt to run away from the player to avoid being attacked, before stopping to attack once again.

The evoker will change the wool color for any sheep within 16 blocks from blue to red.

Fang attack
One of the two forms of attacking the evoker uses is summoning a dozen alligator-like entities out of the ground. This attack has two forms: Offensive and defensive.
 * Offensive Bite
 * When using this attack offensively, the evoker ascends many of these 'alligators' in a horizontal line toward the player or a villager. These 'alligators' bite consecutively after the last one, until the attack finishes.


 * Defensive Bite
 * When using this attack defensively, the evoker ascends many of these 'alligators' in a circle underneath themselves. When using this form of the biting attack, all of the 'alligators' bite in unison.

This attack deals of damage, regardless of armor or enchantments, and do not damage the evokers themselves.

Vex summoning
The other attack the evoker uses is to summon between 2 and 4 vexes per attack when threatened. The evoker will continually summon vexes, even when there are some still alive from the last summoning.

Data values
Evokers have entity data associated with them that contain various properties of the mob. Their entity ID is.

Evocation fangs
The individual entities in an evoker's fang attacks each have a delay. Before the delay is over, the fangs cannot be seen, although unlike truly invisible entities, fangs in warmup still have a visible debug hitbox. After the delay, the fangs expand into existence, snap shut, and shrink out of sight again, dealing magic damage to all creatures standing on the spot. Naturally spawned fangs do not harm Illagers, but player-spawned ones do. Whatever toggle controls this does not (yet) have a data value, and is not saved.

Evocation fangs are not affected by peaceful difficulty.

Data values
Evocation fangs are also entities which have associated entity data. Their entity ID is.
