No, its not a mistake that these have the same stats as Dark Scale Greaves. Long, long, ago there was Mithril Armor. Among these pieces of armor were leggings and vambraces (yeah, I'm dating myself...). They both had the same exact stats and weight. It seems that these are Verant's upgrade to Mithril Leggings and Vambraces.
Go look them up on this site if you like. They were both 10ac 7str 7sv magic 3.5 weight (or something like that)...Personally I think that leg armor should be close to double if not at least 1.5 x the AC of your sleeves (unless you have some sort of 45ac vams or something insane like that.
Wow, grats to you guys! This is the first time I've seen a guild from the Drinal server post a new item to Allakhazam. King's Court rocks. For those of you who don't know, King's Court is one of the three "uber" guilds of the Drinal server.

aye... I used the legs for a long time until i got my barbed ringmail legs recentely. Still... seems that better sleeves are available for the lvl in Velious... legs are a bit harder to come by.
