Aephoenix Boss Battle

 IJA minecraft is an German YouTuber who creates one command creations and showcase them on his channel! He recently hit 100.000 subs and started a one command contest! His vids are english, so make sure to check him out! >> Link to IJA's channel << 

My one command contraption is about a boss battle in wich the player has to defeat, yup, I think you understood it already with the title, me. So, when you are going to summon a clone of myself, he will have some diamond armor, a diamond sword and one special Item, wich I'm gonna explain later. Your goal is to destroy him, thing what, I think should'nt be too hard if you're well prepared. He will then drop the special item.

The special item I was talking about is, what I called, the Power Stick. When you hold it in your hand, a lightning will be summoned, around every 30 seconds, above every hostile mob in a radius of 20 blocks (except the enderdragon, the wither and the boss of my contraption himself). When the Aephoenix Boss is alive he can use it on every player in 20 block radius around him.

First off get the 15w36d snapshot by going into "edit profile" in your MC launcher and then select Snapshot 15w36d under version. Secondly,  you will need a command block: get it using " /give @p minecraft:command_block " (You will also need cheats enabled in your singleplayer world, or operator on a server (vanilla only!).

Having that done, go to My Pastebin and copy the command from there. Paste it into the command block, wich you better put into your spawn chunks (the place where you spawned the first time into your world), and then just activate it. The command block structure should appear next to the first command block, if not then check the instructions above once more. If everything is good you should also have a command block wich appeared next to your initial one, with a button, wich you can use to delete the machine.

When everything is put in place and you're prepared to defeat the boss, you will need to build a totem/little structure in order to summon him. For that you're gonna have to collect 1 gold block, 4 end stone and 4 chorus plants. To build the structure, firstly put the gold block in the middle, then the four end stone at the four edges of the gold block and finally put the chorus plants on top of the end stone (go to this link to see an image).

Once that is done and you think you're ready just throw a nether star on the gold block and the boss should spawn a little time after that (P.S. don't stay next to the totem while waiting for the boss to spawn..). 

-Please note that meanwhile you throw your nether star on the gold block and the boss spawns, the random tick speed is augmented by 500%: plants, grass and trees should be growing faster, as well as leaves be decaying faster.

-Please note that it could happen that the Boss just stay immobile for a moment before walking, this is due to minecraft calculating the path that the entity is going to take, the problem with that is that the game ticks (command blocks, entitys) freeze. If someone know how to fix that, please let me know!
