Lithium Man question

Lithium man

Lithium is the simplest possible metal. The simplest possible ADOM game would be to travel immediately to the CoC, visit the ToEF when necessary and finish the game. No other locations can be visited.

Can the Ogre Cave be visited? DH and AF? Blue dragon caves?

As I understand the only requirement is to not visit dungeons other than CoC and ToEF. Optional side-dungeons are fine, taking as long as you like is fine, etc. It's got a very simple rule to it, which is how the best challenges are
