So, I've made it to a Mansion in survival and was all geared up for the Vindicators, which are typically meant to be super aggressive but as I built a small shed to keep my stuff in and save my spawn a Vindicator waltz past me.

Confused, I left it alone. But, I went into the mansion and found that the vindicators don't attack me on sight, however, the Evokers do. When attacked, they do fight back, but only one is provoked at a time, unlike Pigmen or Wolves.
