I think this is an ongoing problem. See also 4284, 3768, and 4407.

I think this is still at 0% on Steam statistics, so nobody has ever managed to get it, AFAIK.

Yeah just checked and it's at 0%

There was a problem with counting the necessary locations. I have now adjusted this: You need 62 locations for the minimum win (according to my own understanding of ADOM :-) ):

1 - wilderness
50 - caverns of chaos (using the living tree level instead of DH)
4 - ToEF
7 - Mana temple branch

ADOM now checks this number in a hard-coded way (instead of the using the dynamic routine I obviously fumbled before).

Fixed.

Great thank you! But to clarify. Is it ok to get attacked in the wilderness? Also, there is sometime the shortcut in D2-3; would it be ok to use both the shortcut the normal D level? (and imho DH should be fair game but that's your decision ;) )

So if you accidentally descend into DH (and there's no way to predict in advance), you fail Lithium Man because you'll get at least 1 extra level, but you actually didn't do anything wrong, just had a random 50/50 chance mess you up?

What about the (sometimes) path-split in the early CoC? I guess you have to be really really careful to always take the same split direction whenever you change levels?

At the very least, these should be clarified in the achievement text.

Do you have a proposal for a clarification?

I think it should be shortest possible path with the exception of the CoC shortcut and DH. IMHO it's a challenge about making the most out of every bit of resources you find and of your knowledge of the game, which would not be altered by that.

Maybe add something like "(while visiting least amount of dungeons in the process)" at the end?

People typically consider split, dwarven halls and ogre cave as part of caverns of chaos, which are allowed in current description.

Yes, they should definitely be allowed, in particular the split level and DH, where it's just a matter of blind luck. Lithium man is not about getting it right with the 25 % probability to pick the right ones out of two staircases, it's about sticking to the basics.

I at least have always understood the CoC limitation to include everything in that cavern. So that it would allow also Ogre cave and BDC.

Currently(Steam release) it reads:

If you want to specify that CoC does not include DH but does include AF and the MT branch then I'd suggest:

I *think* that covers every location you're allowing. And the presence in there of "AF, DT, MT, and UC" should make it clear that the Ogre Caves, the Dwarven Halls, and the Blue Dragon Caves are not included.

Yes, that achievement contains mild spoilers (there's an Animated Forest?), but anyone looking at achievement descriptions will already see spoilers ("Slay the Chaos God", "Successfully rob the Casino Shop").

Split and DH should be definitely allowed as there's no reasonable way to distinguish them.

IMHO, BDC should not be included.

Split is technically allowed... you just need to mark the stairs, and use the same way.

If number is hardcoded... alowing both parts of split and DH on top of AF, would mean that someone who dodged both can unlock DF and Terinyo, which gives shortcut, PoCC, etc.

Overall, I am for proper implementation, but given the past problems, I gladly take whatever working solution happens to be...

Oh I forgot about OC. Imho everything in CoC shoud be included except BDC.

Just out of curiosity, why would BDC be the only one that should be excluded?
The challenge is about visiting two places - CoC and ToEF. Lithium man allows you to move back and forth in these as much as you want, and also to scum deeper levels if that's your thing. BDC doesn't make the thing easier, just adds a few levels to it. Even if BDC was forbidden, you could still do scumming in DH or the cavern at D:37-ish.

In my case it's purely subjective. That's how I always understood the challenge. BDC is technically a path taken for an ultra, it's quite a big deviation and the challenge is to close the door in the straightforward fashion. As for DH I think there is pretty much a consensus because it would be pure luck. As for OC, I feel that doing the challenge should not preclude doing that quest line, but I'm okay either way. The shortcut I don't care as long as there isn't any issue that would be similar as the one we have right now with Forest-DH.

DH and Wilderness encounters are no taken into account correctly. This feels better than changing the message in a complicated way ;-)
