The speed leggings add a speed boost when applied(simple enough). Good for escaping mobs.
The TNT plate will blow up, but not hurt you, when activated. To activate it, hold one block of TNT. Good for fighting a large amount of mobs at once.
The fire plate, when activated, will create a 9x9 area of fire. To activate it, hold flint and steel. Good for burning down places, and fighting large amounts of mobs.
The magic boots are quite unique. Walking over certain blocks will change that block. The blocks it can change are:
-Dirt, turns into grass
-Cobblestone, turns into stone
-Water(not flowing), turns into ice
-Lava(not flowing), turns into obsidian
-All ores, turns into stone, and gives you the ore
Not much use, but fun to mess around with.
The time helmet will speed up time, every 10 ticks the sun/moon changes position. Good for escaping zombies and skeletons, or just changing the time.
The cape will make you fall slower and take no fall damage, similar to a chicken. You can also fly.
Pressing Space and Escape at the same time will activate the flight, holding Left Control and W will make you fly, and pressing Space will stop the flight. Good for falling from high places, and also extremely fun to mess around with.
The slime helmet gives you the ability to stick to the ceiling. If there is a block above you, after a couple seconds, you will stick. You can travel on the ceiling for a limit of eight blocks, and after the limit you will lose your grip and fall. Good for traveling past pits.
Double Jump Boots
The double jump boots allow you to, well, double jump. Like most double jumping mechanics, simply press Space in midair to double jump. Good for getting up mountains.
The obsidian plate prevents fall damage. I know, it's weird, but it's the way it works. Good for getting down from high places(better than the cape in my opinion).
The diving helmet allows you to breathe underwater. You can sit there for a Minecraft year and you won't drown. Good for obtaining clay, or discovering the ocean in general.
And that's about it! This is my first map, so it may be a little buggy. There are also a few random things lying around from testing. But thanks for veiwing!
