Immortality

I'll use this page for any new special materials that don't find their way into Immortals Handbook products. If you have any suggestions for new special materials then let me know via email or at ENWorld. The Immortals Handbook - EPIC BESTIARY: Volume One includes the material Orichalcum (White Dwarf Star Metal). The Immortals Handbook - GRIMOIRE; will also include an undisclosed number of new special materials. ;-)

Neutronium

One material I didn't have the space to include within the Bestiary, was Neutronium. But I didn't really think there would be a great interest in it anyway, so I wasn't that bothered by its omission. But lately a few people have been asking about it, so following is my best guess as to the properties of Neutronium (by the way, if Anabstercorian and the guys at MIT are reading this feel free to chip in with some thoughts).

Before we begin, its worth noting that the word neutronium is bandied about in sci-fi circles with seemingly reckless abandon. The following wikipedia entry for neutronium, here, lists a number of fictional uses of the metal.

So its worth asking yourself, do you want a close approximation of actual neutronium or just some sort of really dense metal. If its the latter I would suggest you use Orichalcum instead.

NEUTRONIUM (NEW SPECIAL MATERIAL)

This dark grey metal is so dense that even in its solid state its surface appears to have the properties of liquid.

Properties of pure neutronium:

Neutronium is more than 10,000,000,000,000 times heavier than steel (thus a medium longsword made from neutronium would weigh in excess of 20 billion tons)
Neutronium has a hardness of 1500.
Weapons fashioned from Neutronium bypass the first 1500 points of hardness.
Weapons made from it increase their base damage by a factor of 192 (thus a longsword would deal 160d10 as per the Universal Damage Table in the Epic Bestiary: Volume One page 7).
You need a minimum strength of 235 to use neutronium items.
Medium Armour made from pure neutronium grants damage reduction 150/-, Heavy Armour grants damage reduction 300/-.

...more dense than even neutronium!?

While I am no expert, it would seem that there are a handful of materials that are even heavier that neutronium. This includes:

Dark Matter/Quark Matter/Strange Matter (10 times as dense as neutronium)
Black Hole Matter (100 times as dense as neutronium)
Weak Symmetric Matter (Unknown, but somewhere between Black Hole Matter and Strong Symmetric Matter)
Strong Symmetric Matter (About 1E34 times as dense as neutronium, basically the mass of the entire universe in a single object).

N.B. The Dark Matter and Black Hole Matter figures in the above tables are slightly inaccurate, since they depict materials x8 and x64 times more dense than Neutronium rather than x10 and x100 times, respectively. As you might imagine the difference is somewhat tricky to work out.
