Is it possible to export the level, items, monsters?
 

Playing v3.5.1. I've ended up on a level (1150') with feeling 2-9 but have not found anything remotely valuable.
I've used m.a.g. to search for doors/traps covering all parts of the map.
I've used rod of treasure location covering all parts of the map.
Still nothing...

I'd like to just export the level to see what is giving it the 9 rating. Any thoughts?

Cheers.

You can't export a level as such; the best you can do is make a copy of your savefile, and then open that copy and enable debug mode (ctrl-a) to examine it further.

My guess for what has happened is you picked up a deep but not very impressive item - for example a steel helm is a level 40 object.

Sounds good, do you know where the savefile is stored in linux?

Should be in ~/.angband/Angband/save.

You can take a "screenshot" that's pretty good with the ) key.

That screenshot feature is pretty cool.
As a side note, in my distribution of linux (Xubuntu) with Angband 3.5.1 the save file is under:
/var/games/angband/save/

OK thanks, interesting.

Would a +3 ring of digging result in a 9 rating? I've looked through debug mode but can't find any other ego items or stat potions...

So here's what goes into the calculation:

• To get a 9 object feeling, you need a total rating value of 16 million
• For each object, the basic rating is its value, plus 20% for each level out of depth (for the base object kind), divided by 10, squared
• The overall level rating is the sum of all the object ratings, divided by the depth

So for this case let's round up to 25 because it simplifies the maths, and assume the 9 feeling is caused by a single object. Then we need to get to 400 million, which is 20 thousand squared; so our object value has to be 200 thousand - counting the out of depth factor.

Stat potions are 8000, plus 140% for out of depth, or about 20000 - still a factor of ten short. A possible candidate would be say an ego mattock - a level 50 item, so you'd take its value and add 27 * 20 = 540% - it would still need to be valued at about 30000 AU.
