If you're already power gripping a weapon it goes to your inventory anyways, I'm not positive about double gripping though since I haven't used double grip against someone with the exotic lore or a Monk in Dragon. There are sockets out there now though that you can get to make your weapon nodrop though, like the Orb of Betrayal. You also get the nice added affect of having pass door added to you until you remove it from your person.

Obviously the Battlemaster's Blade was the only one on the list that has been there before Warrior Lore and the first Dagger is only nodrop and not both. How do I know when these ID's were made though? My first file of ID's is divided into 1.0 and 2.0 split about a third of the way into it and has the change of the double plated helm from 1.0 to 2.0 and I believe the third change to it as well after Onileon or however began wreaking havok. That was forever ago though.
