This is a compilation of five custom command block creations that I have made so far. They are:

• TNT Bow - explosive arrows
  
• Slime Boots - jump boost
  
• Seven League Boots - speed boost
  
• Floating Feather - levitation
  
• Moon Boots - low grav simulation
  

I compiled the commands using MrGarretto's 1.11 Command Combiner, as well as his Beta Custom Crafting Generator. These commands can be found at https://minecraftcommand.science/profile/tobarr_finn, and I have also included a word document with the commands in them. These commands are free to use, however, they are only intended for single player use. You can use these in a map if you would like, but please leave credit.

Enjoy!
