Use the Hammer to activate hidden redstone mechanisms and kill most of the surrounding mobs instantly.

Put on your new Hover Boots, which allow you to hover in mid-air for two seconds.

An 1.9 advanced version of my old Lens of Truth command. Use the Lens of Truth to unmask hidden blocks or locate fake blocks, which actually aren't there.

Use the Sand Wand to raise sand blocks and get a strength boost while walking on sand.

Use your new Hookshot to pull yourself towards special blocks, which you can set with the GrabBlock spawn-egg. Collect items from a distance and create awesome obstacle courses.

Throw some tnt on the ground to cause explosions, which won't cause any blockdamage but still hurt mobs and players. Furthermore the bombs will only destroy silverfish spawn-blocks, which you can hide in your buildings to create hidden entrances. Place some tnt in your offhand to shoot bomb arrows, which works the same way as the thrown bombs. Hitting a chiseled stonebrick with an arrow will turn all red wool around into redstone blocks for a second. With this feature you can create awesome puzzles and minigames. In addition, you now can pick up your enemy's arrows.

The Crystal Wand can break any emerald block in gamemode 2 and these emerald blocks will drop 'Crystals', which can be placed on iron blocks even in gamemode 2. If an emerald block is placed on top of a 'CrystalAim'-block, you can spawn using a special spawn egg, a redstone block will be set beneath it. With this feature you can create awesome puzzles in your adventure maps.

Hold down shift to charge your forces. Once you hear a short sound, release the shift-button to unleash a Spin Attack, which kills all mobs nearby immediately (doesn't work for players, Wither Bosses and Ender Dragons). After you used this power you need to rest a while, before you can charge your forces again.

This command will add the following items: Bow of Power, Bombs, Grapplinghook, Lens of Truth, Steel Sword, Master Sword, Crystal Wand, Sand Wand, Hammer. Watch the video to see all of the items and their functions. Remember that this command is made for Minecraft mapmakers, which doesn't mean that you aren't allowed to use it in survival :D

Get the Lens of Truth and learn to crouch! Use spawn eggs to create hidden entrances you can only see if you're holding the Lens of Truth or create 1 block tall tunnels you can crouch through.
