If you manage to get the villagers to attack you from having high suspicion, a raid will happen with around 12 villagers attacking at once, the villagers count as heroes and if you are at the endgame, you should be able to create some kill rooms to lure them into and kill them or maybe you have enough good fighters and equipment to fight mano a mano with them.

Check out this guide to see which type of minions can be of great use to have an army against the villager raid: Steam LinkMinion Trait Guide 1.0 By firesidechat

Be aware the villagers are greedy and if they see gold, they will forget about attacking you and take the gold instead and try to escape.

Anyway, you can trigger the villager raid event a few times until this achievement pops, otherwise, heroes only show up in groups of one to four every 3 or 5 days.

A slightly tricky achievement since the game doesnt tell you how to accomplish this.

Out of the 15 monsters you can recruit, the dracula or vampire is the one you need for this achievement since it has the Charm attack skill.

You wont be able to recruit new classes of monsters until you unlock them in the first section of the Crypt by using evilium which is gained by killing victims.

Simply make sure your vamp has more Mind than your target, which is easy if your target is a Basic Victim.

Put your vampire in attack mode and move it close to the room where the victims will enter.
Then, when the victims are distracted (reading bookcases), enter the room with the vampire.
Left Click on the charm skill then Right click on the victim, the victim will now be charmed.
Left Click on the victim (it should have crazy eyes now), you can now control the victim.
Left Click on the Attack icon/circle near the victim's profile on the left, then right click on the other victim to attack it.

Achievement unlocked!

Cheers!
