With this power you've become a Minecraft character - with all the physics it entails but none of the downsides of looking like you crawled out of Minecraft.
You can punch trees into blocks while the entire tree floats in the air. You can break veins of ore with a pickaxe and get a 1 cubic meter block of that material no matter what. You can even shove 1728 cubic meters of diamond into a cubed storage chest!
You also have a limited inventory space consisting of 4 armor slots, 9 hotbar slots for quickly swapping items, and 27 storage slots. Each hotbar and storage slot can hold 64 of the same items in a stack. All items inside the inventory are weightless as well, we can't have you carrying 22 billion pounds of gold after all!
Besides an inventory, you also have a crafting menu. Besides knowing normal recipes found in the base game you are also capable of creating both a Nether and End Portal out of suitable substituted materials.
In addition, you gain the ability to enchant items with an Enchantment Table by using ‘Experience’, which you gain from defeating enemies and crafting items as the fuel, and Lapis Lazuli (or a suitable substitute) as the binding agent for the enchantment.
You have 10 ‘hearts’ that depict your current health and status, and you acquire more with any extra brute powers you may possess. You do not get the ability to respawn unless you have a power allowing it, but if you do, you will respawn back in your bed after dying.
In combat, you deal slight knockback damage when hitting an enemy. You gain invincibility frames for a short duration upon being hit, and can critically strike an enemy, dealing additional damage, every so often.
You can selectively toggle which parts of this power are in effect at any given time, meaning you aren’t stuck to only crafting cubed objects permanently, nor do all of your creations have to defy gravity.
