List of unforgable artifacts?

[Argitoth]

Don't forget the Precious.

dood! The precious should've been more akin to Lord of the Rings... The precious gives you extra attack and strength. It should also make you ethereal and give you insanity

Speaking of which, there isn't such thing as invisibility in Dom3. Man, I never thought of that! There should be an invisibility spell!

Invisibility: +30 stealth, hard for normal-seeing units to hit, any blind or in some cases darkvision negates the effect of invisibility.

I guess glamour would kinda be like invisibility, so would being ethereal.
