This armor pack is OP, by all means, it's twice as good as diamond armor, and gives you a bunch of effects.
To start the mod, you'll want to first go looking for dark iron ore, found in any biome in the overworld, but only from layers 16 to 48.
Then, you'll want to go to the nether, and look for glowing red netherrack, called bleeding netherrack.
Also, you'll want some obsidian, not much, just a little bit.
You can get the materials by just mining the bleeding netherrack, but you need to smelt the dark iron ore, then, you'll want to arrange the materials in the way that the pictures show, to get your tools and armor. But just do the shovel recipe with dark iron for the mace.
It also of course, adds blocks for the bloodgem(bleeding netherrack) and dark iron.
The longsword has the highest attack speed, but the least damage
The mace has medium damage compared to the other two, and same with attack speed, but sets opponents on fire.
And the warhammer has the lowest attack speed, but deals the most damage, and gives your opponents slowness.
They all have base spell effects that they give when hitting an enemy, and the warhammer gives 5 levels per block broken.
If you want to use this in a modpack, go ahead, as long as you put my name in it somewhere.
