The silent killer

The silent killer would be a new boss a very strong one too it would spawn in a stronghold it would guard the end portal to stop you from getting it they would wear a black outfit with only a little eye holes weapons of choice are two enchanted iron swords not only that they would be very skilled they will stay out of sight of the player they will strike the players back it will trick the player to look somewhere and then I hit the player in the back and dash away fast not to mention they favor dark areas so they will purposely hide in dark areas overall I think this can be a good boss so a nice little boss to warm up the player before they enter the end
