Ruby

Rubies are semi-rare red gems that can be obtained by smelting its ore. It can be crafted to Ruby Tools, but using Blaze Rods instead. It can also be crafted to a design block, or recycled back. When placed onto Nitro, it directly ignites it like Flint and Steel would. They can be crafted to make Glowstone Sticks, together with Blaze Rods.

Ruby Tools
The same way to craft normal tools, but with Blaze Rods and Rubies instead.
