Patrol

An illager patrol is a naturally spawning group of illagers.

Spawning
Illager patrols spawn as a group of five mobs including an illager beast plus a maximum of four other pillagers (weight 55) or vindicators (weight 27) up to five blocks away from the illager beast, one of which is the patrol "leader".

Illager patrols can spawn in plains, taiga, desert and savanna biomes as well as their variants.

The patrol leader will have an illager banner on their head.

Behavior
The patrol leader can ride the illager beast. Patrols will seek out villages and attack villagers.
