# Talk:Potion of object detection
Blessed Effect?
The blessed effect is stated as "You know the appearance of all objects on that level (and in your inventory) as if you had seen them." Can someone please explain the meaning of this? Is it just that the farlook command ([;]) reports it as seen, or am I missing something? -- Kalon 07:01, 7 April 2008 (UTC)

Cursed Effect?
I just had something strange happen in my game.  I drank a potion of object detection (I didn't BUC test it, so I don't know if it was cursed or not).  The potion showed a bunch of gems and coins inside the walls, plus a few items in rooms I already explored.  When I went back to those rooms the items disappeared, and when I dug out to the gems and gold they also disappeared.  There were no other monsters on the level, so I'm not entirely sure where these items went, unless a cursed potion creates "ghost" images of items that aren't really there.  --MadDawg2552 20:56, 5 October 2008 (UTC)

Just to clarify: did you dig a pit in the locations where the items were located? This is a common problem with detection, specifically with gold and gems in rock. Additionally, remember that monster inventories show up too, so a wandering monster with a helmet will appear as a helmet in a room, and then the helmet will disappear when you sight the room. -- Kalon 22:19, 6 October 2008 (UTC)
This is probably what happened.  I did eventually find an elf wandering around, so he might have been one of the ghost items I saw, and he probably picked up the other stuff before I could get to it.  I didn't try digging into the floor for the coins and gems.  I always thought they were just embedded in the wall and digging it away would reveal them.  At least, that's how it's always worked for me up until now, though I don't usually try to dig that stuff out unless I'm in dire need of some extra money.  --MadDawg2552 18:56, 10 October 2008 (UTC)
The strange ordering of the table (uncursed-blessed-cursed) is deliberate.
This article describes the effects of quaffing an uncursed potion, then a blessed one, then a cursed one. This was a deliberate choice on my part. While unusual, I believe this order makes the effects of the potion easier to understand. Blackcustard (talk) 03:19, 2 September 2012 (UTC)
