Thanks so much for taking the time to lay out all of this. You bring up some really valid points about how new players interpret things, and it's a good reminder to myself that just because I know how everything works doesn't mean it's intuitive for someone encountering it for the first time.
I'll be updating the descriptions for both the Flask and the Violetheart Pendant in the next patch.
As for the Mageflare Rune, yeah that has been a tricky one. I've updated the description a couple of times now and it's still causing confusion. I'd definitely welcome any suggestions you or others have for a clearer way to explain it, ideally something that instantly signals it's a temporary darkness removing effect. So far I have tried "Reveals the whole map temporarily." which was too vague, then we have the current one which is "Removes darkness until the next dig." where the players might confuse "next dig" as the next trip down from the surface.
Regarding the Stone or Granite zones, It's interesting that the texture gave off that impression. The color seems fine to me as they are shades of gray, but maybe we could use some pattern update for the cells. A full graphics rework might be something to consider down the line, but for now the focus is still on getting new content and improvements out regularly.
Thanks again for such a detailed and constructive breakdown, it really helps. Do let me know if you find any other unintuitive or out-of-place descriptions.
