Right now, i'm going over the character sheets, and in all honesty, i don't get all the fuss about Tordor's coat. If it's a coat woven out of spider silk, no matter how durable and resistant to abrasion, it isn't even going to be as thick or heavy or dense as a Kevlar vest, so a mighty good whack from any kind of weapon will deliver nigh unhindered blunt force trauma. The only thing it will reliably protect from is penetration.
