Loot (tagalong) whoring in Karnor's Castle?

[Telemakus]

Hey all, I wanted to ask about the no drops in Karnor's Castle, specifically the Jarsath Scale items.

Do these items often rot, such that a newbie Cleric and Paladin could come in and loot what would otherwise go to waste? Is it particularly difficult to do so if yes? What level is best for that?

I'm not really a big money baller, but the quest for gear is fun for me even if it means just exploring and seeing what scraps I can pick up here and there, so I'm really just looking for ways to go about that.

Thank you!
