Yeh same here, I managed halls of stone once before but wouldnt have gone back there again from choice. Ive done it 3 times now since the patch when its come up as random dungeon.

The occulus still beat me though, Pre patch I never even zoned into there, just the thought of vehicle combat sends shivers down my spine. I had a shot at it yesterday though, 1 shotting the first 3 noob bosses then wiping at 60% on eregos because I didnt know about the arcane explosion thingy he does. I was also on 5 bronze drakes as I figured I might be able to zerg him down before he did anything special. It didnt work out but I will try the 4 emerald and 1 ruby next time

EDIT: have also read the tactics for eregos now also and seen that you can buff the drakes up, that will be a massive help too
