The Myticiah Mod adds one new material to the game , appropriately named Myticiah. Myticiah tools are 2 levels higher than diamond.
Myticiah on average spawns one ore in every chunk, however it only generates in forest biomes.
Smelting a Myticiah Ore Block gives you a single Myticiah nugget. To be able to craft tools, you must have 4 Myticiah Nuggets in a diamond shape, and the rest of the table filled with emeralds, as seen below:

Then, you can use this Myticiah Ore item to craft overpowered tools, using the same recipe as diamonds, gold, and wood etc, except replacing the material block/item with Myticiah Ores.
So where did this come from?
This mod came from the idea of @grandboyXL on the Minecraft Forum so I decided to develop it.
