Yes, visual cues to the shrubery subdungeon just aren't there
I just ran into the Golem glyph converison subdungeon. It converted Endiswall into a realy nice piece of armor (useless for the shifting passages I found him in but still), and WONNAFYT into 3 Slayer Wands (whooop, I was on an "Unstoppable" quest, and it allows for "slaying" high level enemies). What else does it convert and into what, does anyone know?
