I managed to clear Ruby Sanctum 10 on Larthas. It took a few wipes due to a few silly mistakes; one of them on my part, but in the end, we managed to kill Halion. Nothing dropped for me, but I got a bunch of Frost Emblems and an achievement so it was definitely worth it.
Also, my money supply dropped suddenly. Someone flooded the market with cheap enchanting mats so I had to buy it all out. The plus is, I probably wont be needing fresh ones for a week or so. I managed to make 3-4 of each scroll with the mats I bought. I also decided to try my luck on some of the old world twin enchants. The profit mating is huge, but I'm not sure how well they sell.
