What is the hardest dungeon in the game?

[Tecmos Deception]

HS does have hard mechanics. But knowledge can counter those. SG has hard mechanics that knowledge cannot counter. You're just confusing the issue if you can't realize what "hard" is supposed to mean in the context of the subject and first post.

It takes 0-1 wipes in HS for a competent group to realize they they probably should have a contingency plan in event of a wipe. Then the thing that you've been carrying on about for pages is nearly a non-issue. And even that first CR isn't that bad unless your group was like, 6 warriors or some shit so that you can't pick locks or invis or summon corpses or kill (albeit more slowly) without gear, etc.

But since SG is difficult to crawl through/farm/etc (you know, hard), even if you know how to move through the zone or do a CR or whatever, it is harder.

As for bringing ntov into this? I hope you're just trolling and not actually afflicted with a mental impairment.
