So i used a bug that make evokers passive, a good variant(if the vexes are nightmares), i don't know why i entered from the top, it worked the terrible, i entered the library with zombie villagers(why?), later i found some vindicators but i screenshot-ed the plan.



But i prefer evokers than vindicators because they won't attack you from the back or in team. Try to find a secret room, they have good loot, don't try the chest room , they're useless if you are bad equipped and you lose pvps try to free the allays first.
