I don't know if it'll look really stupid with the Aetherial shield, a core element of that path

I'll take a quick look at the Creation Kit, just a minute

Don't worry about it man. Hopefully it isn't more than a week until it comes out on PC (in 4 days it's 1 month since the XBox release).

Ok, so here's what's going on. This screenshot here is of the enchantment, which checks the time and then activates a magic effect here:

You'll notice that the 'effect archetype' is a value modifier and the associated value is Weapon Speed. However, since the effect is instantaneous and effectively has no duration it actually does nothing.

You could use Heavy Chitin also, looks nice enough I suppose, and is the main armor genre I think of when I think of morrowind, and has better stats if I remember right

Ponty, 

Why does the Twilight Defender not wear a suit of Ebony. Also, for the Dusk sword why not an ebony because ebony is like the blackness of night.
