Orium is an alloy created by combining dragonshards and mithral. While it can be forged into weapons and armor it is much more common to be made into body augmentations.
There are two varieties of orium: Red and Black
Red Orium is infused with a spell and is common with laborers and soldiers. Here is an example of a common augs:
Orforged Arm of Magic Missile
With this arm, you can use an action to expend 1 to 3 of its 7 charges to cast the magic missile spell without using any components. For 1 charge, you cast the spell as if you used a 1st-level spell slot, and you increase the spell slot level by one for each additional charge you spend.
The arm regains 1d6 + 1 expended charges each day at dawn. However, if you expend the arm’s last charge, roll a d20. On a 1, the arm goes haywire and must be repaired.
Orforged Legs of Jump
With these legs, your walking speed becomes 30 feet, unless your walking speed is higher, and your speed isn’t reduced if you are encumbered or wearing heavy armor. In addition, you can jump three times the normal distance, though you can’t jump farther than your remaining movement would allow.
Black Orium augmentations contain a bound elemental. They are rare and considered strictly “military grade” because of their power. Here are some examples:
Earth Bound Orforged Arms
Your Strength score is 19 with these arm augmentation. You may also burrow through any earthen material softer than solid stone. This burrowing ability recharges with a short rest.
Air Bound Orforged Spine
This aug has 3 charges, and it regains 1d3 expended charges daily at dawn. When you fail a Dexterity saving throw you can use your reaction to expend 1 of its charges to succeed on that saving throw instead.
