Shadeglass weapons question.

[SirSolomon]

Let's say I have a shadeglass weapon and I attack. I roll Hammer and crit. The Defender rolls 1 crit. Does it still do the extra damage or just normal damage?

[Tutenkharnage]

That's a critical hit. See the last paragraph of the "Critical Successes" callout on page 20 of the rulebook.
