I made a box trap. It takes forever to set up but it's 9001 dmg.
Steps:
-Prop up box with stick.
-Stick a fake scary face or egg dance under it.
-Hide behind the bush provided. (amazing how no one thinks a bush in a base is suspicious)
-Wait for someone to waltz on by.
-Pull the rope provided.
-Get 1 kill.
-Spend 3 minutes setting it up again.
