I gotta get back into Dark Spire now that everyone's playing it! The setup I was having decent luck with was warrior in the front, everyone else in the back. Get your warrior as low an AC as you can
and just nuke from the back. The theif can use a bow and can also "hide" and then backstab an enemy from the backrow the next turn after hiding - but I have better luck just shooting.
Mostly when I play the DS I play the japanese import for Picross 3D ("import" through the internet!!! aahahaha) it's pretty cool. I still might fundamentally be missing something that would make it easier, but overall it's pretty cool puzzle game. Maybe Johnny can translate the directions for me.
CON! Got my plane ticket, I pre-regged, I'm READY!!!!
