hi, this is the spiky armor set command, this must be pasted in a command

block. to get a command block type in chat :

/give @p Minecraft:command_block

now we got a command block, place it down, then paste the command, now press [  down  ] button then send a redstone signal to activate the

command block then you see a armor stand on top of it. to get everything off of it is to hit it until it brakes {make sure your not in creative}

and then your done ! now go have fun and have a nice day ^,^
