My group is about to descend into the depths (yes, *those* Depths) and I'd like to find some good maps and tiles for the random tunnels and caves. So far (after browsing the market) I'm planning to get "Save vs Caves", but I'd like to know if people have other suggestions. What I'm looking for- geomorphic, top down (not isometric) caverns, tunnels, and passages to be used in the Underdark. Preferably maps and terrain features only, but if the pack has some extras, that's OK as long as it's mostly maps. I will be adding dynamic lighting as well. I'd prefer to hear from people who have used the map packs they're recommending (I'm assuming that the creators of the packs count as having used them). Because of some issues I've had with over cluttered maps slowing the game down, I intend to keep non-map layer clutter to a minimum. Thanks for any suggestions, and please let me know if I put this in the wrong forum.
