Cursed Unknowns is a mod that adds whatever I can think of.
May 21 2021:
So far Cursed Unknowns brings 3 new ores and 4 weapons.
Cuboid Ore - can be mined with a stone pick and above, drops 1 Cuboid and spawns in clusters of 3 once per chunk in the Overworld
Nanoid Ore - can be mined with an iron pick and above, drops 2 Nanoids and spawns in clusters of 2 twice per chunk in the Nether
Asteroid Ore - can be mined with a diamond pick and above, drops 3 Asteroids and spawns once 3 times per chunk in the End
These 3 new ores can be turned into blocks by putting 9 of them in a crafting table, the same way you get most other ore blocks. That yields 3 new blocks; Block of Cuboid, Block of Nanoid, and Block of Asteroid.
The Wooden Bat is the new weapon that's added, while its upgrades being the other three.
The standard Wooden Bat can be crafted by placing planks in the top right and middle of the crafting table while placing a stick in the bottom left. Any type of wood can be used to make a Bat.
1st upgrade: Combine a Wooden Bat and an iron ingot in a smithing table to get an Iron Bat.
2nd upgrade: Surround an Iron Bat with iron bars in a crafting table to get a Spiked Iron Bat.
3rd upgrade. Combine a Spiked Iron Bat with a netherite ingot in a smithing table to get a Spiked Netherite Bat.
A Wooden Bat deals 5 damage(2.5 hearts).
An Iron Bat deals 7 damage(3.5 hearts).
A Spiked Iron Bat deals 9 damage(4.5 hearts).
A Spiked Netherite Bat deals 11 damage(5.5 hearts).
