Wand of digging

This wand will produce a Digging ray with range 6. This does not deal damage (except to Earth Elementals), but instead modifies the dungeon. This can destroy walls, stone, boulders, or viewports, reveal secret doors, break through ice, make a hole (a pit on some levels), break you loose if you're buried, and has useful effects in a couple of other special cases. It does not bounce.
