Minecraft wiki entry for Illager, associated text: Pillagers and ravagers do not purposefully attack other illagers. However, non-pillagers and non-ravagers do attack pillagers who hit them with missed arrows.[3] Vindicators and evokers retaliate against a pillager if the pillager accidentally hits the vindicator or evoker with an arrow, although the evoker fang deals no damage to pillagers. Vexes summoned by an injured evoker can still attack the pillager.
