I suggest you take a look at Phantesial, the old blade of Phantos, one-time lord of all fantasy. He gave his life in a battle some ten thousand years ago against a being born of the nightmares of the insane. Even all these centuries later, it still pulses with the power he himself instilled in it. It does not cut per say, but instead slices the very spirit of the flesh, and when spirit shatters, so must flesh follow. Only the spirits of those of evil inclination can be harmed by it.
The Keildan Blades appear to be in this collection as well...they are an interesting pair. Weilded separately, they possess no more power than a butter knife, but when weilded together, they are a force to fear. One blade channels the elements of ice and water, while the other channels the elements of fire and lighning. While neither blade can prevail against all foes, you can rest assured that at least one will. And, they were forged by the late swordsmith Madros, rest his soul, whos blades never dull or tarnish.
Ah yes, I remember this old shield...do you know of the Aliens of the films by the same name (Alien, Aliens, Alien 3, Aline Ressurection)? Well, they do exist, but fortunately not in your plane. This shield and armour set are made of their hides, and are impervious to any chemical attack. Acid, boiling substances of all kinds, none can penetrate their skin. And, since their hides are quite light and thin for their strength level, they weigh very little.
Anything else you wish to know more about?
