When you do a sweeping attack to an enemy on and there is an enemy on the other-side of a corner, it will hit the enemy, and there is a possibility that the enemy can be killed

to do this:

1. make a 2 by 2 space

1. place 2 blocks high in separate sides with glass (do not place next to each other)

1. place an enemy on each unfilled sides, seal them

1. get to one enemy as close as possible

1. do a sweeping attack to the enemy

to make this simple:

The  ""  are the blocks, the  ""  are the enemies and the  "" is you

(please combine the large space)
