About this project
What does Insane items add?
Insane items and many other things!
This mod adds a wide variety of items based on different themes. Let’s start with the basics: what the mod adds specifically, items that are better than Netherite.
To craft these items, you first need to create a biome using a block of Cursed Flesh, then wait for it to spread so you can mine Blood Ore; after that, you must craft standard Blood gear and upgrade it to Netherite.
Bloody tools provide regeneration when hitting mobs.
Cursed chests:
The mod also features cursed chests, which can yield either items or various unpleasant surprises. When you interact with these chests, items spill out directly from them there is no other way to open them. Cursed chests can be found throughout the world or crafted.

The mod also adds structures, one of which is a small house on a hill.

The house has a basement, cursed chests, and monsters, so you need to be careful.
The mod also introduces bleeding and leg fractures, both of which can occur during gameplay. You have a 10% chance of starting to bleed if you take damage from any mob while your health is below 11 points. While the bleeding effect is active, it will very slowly drain your health and cause your heart containers to appear empty. A leg fracture, which can be sustained by falling from a great height, simply slows your movement slightly. Both effects will wear off over time, or they can be cured using milk, bandages, honey, or pills. Note that a leg fracture cannot be treated with standard bandages; you will need improved ones.

The mod includes achievements that might help you get the hang of it.
The mod adds a whole bunch of other things not mentioned in the description for example, you can eat flowers, or come across stones in caves that fall through when you step on them.
