"Attach to target legend. Attached legend gets +4 hit points and can defend any of your zones."

For Cataclysm multiplayer, an attack on a fulcrum is considered and attack on your battlefield ZONE. So by extension, wouldn't the legend with this attachment be able to defend the fulcrum in his battlefield? I sure hope so, because I'm making a Helborg deck for my friend for the next game night and legends are hard enough to field as it is in Cataclysm...

Correct. This is the only way for a legend to defend a fulcrum, so it's even in the FAQ.

Thanks Mallumo! I have read the FAQs, but it's been a while...don't have quite enough motivation to dive back in to that monster again.

I only knew it cause I saw it when double-checking before replying. It's been some time.
