About this project
What does Klsts' Nether Utilities add?
Have you ever felt the Nether Biomes don't have much things to do once you explore them once? No reaseon to revisit them?
This mods aims to make the Nether experience more enjoyable by adding cool resources and features to Nether biomes.
There 4 new resources, which can only be found in their respective biome and can't be placed anywhere else (like Budding Amethyst) . This resources are:
- Crimson Truffles. Found on fallen fungi on Crimson Forests. When eaten will extinguis the player.
- Warped Truffles. Found on fallen fungi on Warped Forests. When eaten will despawn nearby Endermen.
- Ignite. Found on Ignite Crystals on Basalt Deltas. Has many uses, such as creating a block which crystallices lava nearby!
- Lost Souls. May appear when a mob is killed, only on Soul Sand Valleys. Used to craft soul-related items, and more.

There are some new Tools and Weapons, some can be found in loot, others are craftable.

Another resource is Warped Nether Wart, which generates rarely on Warped Forests and can be used to enhance the duration of "long potions" (most long potions are 8 minutes, the enhanced versions are 20 minutes).

New Nether Biome! Mimic Plains: a odd place that may remind you of the Overworld... But is make from crystal and rocks. The new mobs in the biome also look and act similar to some Overworld mobs, but don't be fooled!

Also there is a new structure called the Bone Temple, which has a Bone Vault that spawns loot multiple times when feeding it bones.

There are other features/structures to make it more fun to explore (some of them also have loot!).
Some of this structures may generate in all the Nether, others are biome specific.

And finally there are new biome specific mobs, to enhance the atmosfere of the biomes. Theese are:






Also other important changes:
-Piglins can now barter Netherite Hoes (1 in 500) and other items of the mod
-Added some items of the mod to Nether Fortresses loot
-Added new gamerule Harder Wither. Increases the Wither health, makes it spawn Wither Skeletons when at half heath, teleports it away when stuck in a block...
-Ancient Saplins may be dropped by Piglin Brutes.
I hope you like the mod! Any feedback is apreciated!
