Bexla's Enhanced Ores is a Work-In-Progress mod that adds new ores. Currently, there's still a lot of testing, balancing and missing content (like structures and other ores) to be done, but it's stable enough to be published
If you feel like giving some ideas or any kind of feedback, feel free to comment on this page
Currently, this mod adds:
1- Platinum: Tools ignore 30% of target's armor
2- Osmium: Tools and armor regenerate themselves
3- Palladium: Armor grants regeneration, has a special item called "palladium charm" that heals the player when health is lower than 50%
4- Thorium: Acts as a magic-like ore, armor grants resistance when health is less than 70%, thorium block can emit a redstone signal and gives 9 enchanting points to a enchanting table (which would be equal to 9 bookshelves, reducing the amount of space needed), has no tools
5- Cobalt: Items can't burn, armor grants fire resistance, which only runs out once you enter lava or fire for more than 9 seconds
6- Bismuth: Increased damage on "Undead" enemies, has a special item called "bismuth catalyst" that serves as a potion enhancer, has no armor
7- Manganese: Focused on construction, armor grants slow fall, +1 block of step height and +3 block reach, has no sword, stronger than netherite
8- Chlorophyte (yes, the same one from terraria): Armor grants regeneration if under the sun, tools cause poison on area, stronger than netherite
10- Titanium: Slow items and armor, tools have extremely high damage and durability, stronger than netherite
also, there's a new type of stone called "Amphibolite", which is a stronger version of deepslate that contains ores like titanium
