UPDATE: NPC Cage Traps

[Mooncalf]

There's a new item available in the karma shop that lets you lure in and trap random NPCs during each sunrise cycle (every day).

These 'Enemy Cage Traps' will lure in anything between 0 and 2 enemies every day, and these enemies can be absolutely anything (though the more common enemies are more likely to show up).

Trapped enemies will disappear during the next sunrise cycle, if they haven't been dealt with already. So one thing you should keep in mind is that somebody else could kill these enemies before you do. You should also note that you can only place these squares in public buildings which you own. So for example, shops or anything similar that's open to the public. If humans spawn in your building, you can place these cages there.

To place an enemy cage trap, access your lair control panel by clicking on the key icon while you're standing in your lair, and select the cage from the "place item" drop down menu. You can retrieve the cages using the same lair control panel, if you want to move them later.
