Wand of digging
A magical device which drills tunnels through unworked rock. |
A wand of digging will remove rock walls in a straight line in the direction zapped. It affects only rock walls, whether normal, transparent or translucent. It will have no effect on non-rock walls; e.g., stone walls, metal walls, crystal walls, beeswax, statues, "unnaturally hard" walls, etc.
A wand of digging is quite useful for digging passages into otherwise inaccessible areas, to escape incoming enemies, or to create corridors so as to fight only one enemy at a time when faced with a group. Equally, it can be used to broaden existing corridors to increase access to a monster (say, by a summoner aiding his horde).
