It's Not Copper Tools

2.0

Added Marrow, Igneum, and Ash. Also added Carved, Chiseled, Slab/Stair, and Brick variants for Igneum.

Added geysers: dangerous blocks found in the nether that also happen to make good evil lair decorations.

They come in two varieties, igneum and netherrack, with different properties. Igneum geysers will incinerate your enemies, while netherrack geysers will only scald them to death. How polite of them!

Added a toggle for the flavor text under item names.

Added two new types of tree, obtained by revitalizing fossils found in the nether!

Ashwood trees: tall, willow-like trees with gray wood, blue bark and silvery leaves. Also often the home to firebugs. Seal a firebug in a glass jar forever! See if I care!
Nether Mahogany trees: short, branching trees with purple wood, purple bark, and lavender leaves. Their sap is quite volatile, being usable as an alternative to flint and steel or to craft torches!

Added conditional music, and 5 new tracks from C418 that only play in the nether.

These can be toggled off to restore vanilla (or any other mod's) behaviour.

Added Ivory, a new nether ore used for decoration (for now).

It has a full blockset like igneum does.

Added the IGNEUM POOLS!

A brand new biome found in the nether, covered in ash and constructed from igneum.
Tall pools of lava and jets of flame from the ground make it a little more dangerous to traverse than the wastes.
However, if you look carefully you might find a special fossil...
Big glowstone pillars! Cause they look cool ::>
The nether wastes have also seen some additions... Look out for the steam vents and look EXTRA out for another type of fossil.
Ivory and Marrow can also be found in the nether wastes! Lots of bones there!

Added dungeons to the nether!

They're like the overworld ones!
But with better loot!
And a new exclusive block, cracked igneum bricks!
If you want to go hunt them down!

Added new mobs to the nether too!

Ash slimes can be found hopping around the Igneum Pools. They act mostly like regular slimes, though they drop mahogany sap and have a chance to set you on fire on hit!
Huntsmen can be found wandering aimlessly about the Nether Wastes. They act like skeletons, but they're a bit more dangerous on account of their flaming arrows. Try not to burn to death.
