How do you get all of these items:

Find Ruby, Sapphire, Opal, Tungsten and Flamestone ores in caves. 

Find Ender Geodes in the End Obsidian Pillars. (Whatever geodes spawn will be the ONLY End Crystals you will get in that world) You will need a Crystal Harvester to mine these. Diamond and below are not strong enough.

Mining a Ruby ore will drop a Ruby Chunk, which when smelted will give you a Ruby. 

Mining a Sapphire ore will drop Encased Sapphire. Smelt the encased Sapphire to get a Sapphire and a Sapphire Geode Crust. Place the Sapphire Geode Crust in anywhere craftable to receive Geode Dust.

Mining an Opal ore will drop an Opal (no smelting is needed). Combine an Opal with Geode Dust to create an enchanted Opal.

Mining Tungsten ore will drop Raw Tungsten. Place the raw tungsten and a metal cast into a Cast Forge to create Tungsten Metal Ingots. Combine 9 tungsten ingots to create a Tungsten Metal Block. 

Mining Flamestone ore will drop Flamestone ore, smelt the ore to get Flamestone. Flamestone is a fuel that last MUCH longer than coal or lava.

Putting an End Crystal by itself into a crafting area will give you 4 Ender Pearls.

Create steel by smelting iron ingots in a furnace.

Combine 9 steel ingots to create a steel block.

Create a Cast Forge by combining 6 steel ingots in the bottom of the crafting table and placing 3 steel blocks at the top.

Create an Opal Healer by combining to two sticks and an enchanted Opal. (Shovel formation)

Create a Crystal Harvester by surrounding a diamond picaxe in rubies in the crafting table. 

Create a Black Steel Sword by smelting steel in a blast furnace. You will then get reinforced steel. Smelt the reinforced steel to get a reinforced steel ingot. Combine the reinforced steel ingot with a metal cast in the Cast Forge to get Black Steel Ingots. Place a stick and two Black Steel Ingots in sword formation.

Rarity:

Tungsten - Common

What does the Opal Healer do?

The Opal Healer converts XP and Opals into health. 

Youll still be able to heal without XP however, you still need Opals in your inventory to use the healer. Every time you use the healer, an opal will be removed from your inventory. Use the Opal Healer too much and you'll be left with no XP.

id love to hear both positive and negative feedback on how to make the mod better. Goodluck. Hope this adds to your mc experience.
