Shattered Kingdoms

Armor type: lightest
Armor class: about the same as water if not lower
minimum level: 35

It's more of a thematic change. Given that energy armor is getting rarer and rarer plus there are so many items that -are- made of light or shadow.

It's a good chance to get some nifty looking armor at relatively low levels as well as fix so many items whose materials do not match their description.
(a vest made of woven shadow is made of mithril and size medium.)

I'd rather see something skinnable.

there are shadow monsters made of ink.
