Minecraft wiki entry for Gathering_resources_on_peaceful_difficulty, associated text: On high difficulty levels, vindicators deal the second most melee damage of any mob‌[Java Edition only](first being iron golem). However, like evokers, they do not attack players when on Peaceful difficulty, but they will still be hostile towards villagers, just like they are on other difficulties. Vindicators have a high chance of dropping an emerald upon death, and they also have a lesser chance of dropping their iron axe which can be enchanted.‌[Bedrock Edition only]
