DOS is looking pretty good. One concern: I've spent what seems like hours wandering the starter/tutorial dungeon, mostly finding broken pottery that I have to pound away on manually--attacking it with a weapon breaks the weapon, and there's rarely any reward. Yes, I got burned even after putting out the fire with the water barrels, so learning to wait until the smoke stopped was useful. But I've not yet encountered any enemies. It mostly seems like miles and miles of nothing but miles and miles.
Well it's a tutorial dungeon so I'm not surprised it lacks in loot, as for breaking your weapon....well, I haven't played the beta(mainly because I don't do Steam) but I'd suggest trying magic attacks or just with the bare hands(yeah not a smart idea irl) to see if you can save your weapon that way. Smoke does seem like something that would hurt the lungs so I doubt that's a bug. As for enemies, I think they'll be added in for launch at least I seem to remember them saying they would but I could be wrong.
