The Polarite Mod
by sr_steve
The Polarite Mod adds Polarite, an ore found only underwater that has magnetic properties, plus Hammers and magnet-reactive blocks and armor for NeoForge 1.21.8.
What it does
Polarite generates in the ocean at depths the author describes as reachable, so it is found by searching underwater rather than in caves or specific biomes. A stone pickaxe mines the raw ore, which is smelted into an ingot. From the ingot, players craft a Polarite block, tools and an armor set, and Magnetstone, a new block made by surrounding an ingot with stone blocks at a crafting table.
Polarite interacts with magnetism. A Polarite block attracts and moves nearby blocks, which lets observers and other redstone parts drive more complex machines and farms. The Hammer is a separate tool type that favors slow, heavy strikes: it has low attack speed and high damage, reaching up to 11 health points, and a hit with it sends a shockwave that works with Magnetstone.
The mod is client and server, so the server and every player need it. It is published for NeoForge only, with one game version, 1.21.8, and its latest file is 0.0.0. The mod is released under All rights reserved and is not open source.

What the author says
So, I am going to upload these so called 'death versions' for all of my mods. The reason these exist and the reason I am uploading them is because they were in-development versions of the mods, that I managed to salvage because I made copies of it on my Minecraft mods folder when testing. Unfortunately, I used a PC…
