This is an chest for boss battles, basically its one command to get you some items to be ready, just in case if you don't want to go through the trouble to make an account so you can make one or if you don't want to get multiple stacks and also have idle time to swap things out.
PS. I couldn't make this Minifyed automatically,so you have to press the button for it to be minifyed. :( but, naturally i do, so you can expect most of them being already minifyed. Sorry for the inconvenience. :(
