Completely stumped...(spoiler)

'Kay...in the main story, I've reached the hidden passage below the graveyard next to the transformed temple...

Now what? I've searched the passage, and found two diggable walls, as well as a hidden switch that opens a passage to an empty room. I've even viewed the whole map with debug mode, and nothing shows.

Is this there currently no further content, or am I missing something?

Also, I noticed a "potion of cure mutation." What does this do, exactly? AFAIK, nothing causes mutation...

You probably found the wrong passage(there's actually two dungeons hidden in the graveyard), the correct one only has a single diggable wall. The one you've found is related to a different quest, which you probably haven't found yet.

The potion of cure mutations reverts the stats changes of Radioactivity attacks. You probably won't encounter monsters that uses it until depth 40, and it only starts becoming a real threat in depth 50+.

That is extremely helpful. Manythanks.

And I can't wait to see the mutations...muhaha.
