One more for the road...

Thanks Mickey. I don't know what actual doors (ETC.) the letters refer to but the keys of B and lockpicks being used a number of times will be something I'll keep in mind. Having a BOULDER??? in your inventory??? Ha. I'd better invest in a few 'strength' potions, right?

H172 - THE BEST DOOR
A valuable treasure is needed.
This door will only open for a party with the Fighter Gem.

Carrying a boulder to this point from one of the earlier floors
and charging to (N) allows the party to avoid fighting a horde
of worms. This is the 'Fighters Gem' that will open the door.

I've been searching for the animated armor area. I'm hoping they continue to repopulate.
I've also tried to revisit the dragon area, with all the false walls, but haven't been able to find it again.
I thought they were both in the KU way.
P.S. Mickey: I've been carrying around a boulder and keeping both characters bolstered in the strength area.
I'm enjoying the extra damage I deliver.

The Death Knights are in Ku, if you're talking about the ones guarding Executioner (it's near the "No Fireballs" area if that helps)> The Dragon Maze is in Ros, however.
