Slave

Slaves (aka Farmers) usually spawn in and around farms and in crop fields. They carry no weapon, will not attack you and will flee if you scare them. It is possible to kill them and usually you won't be punished for that except for the wasted ammo as they will not drop any loot.

The first boss will use slaves as a human shield. Instinctively you would try to kill themso you can hit the boss. But if you kill them, the boss will call in new ones. Some of these will even start attacking you. You can combat this by avoiding hitting them. If you do not hurt them they will not hurt you. You can move through the group of minions without being harmed. If you get too close to slaves they will try to get away from you, which allows you to hit the boss.
