Battle for the Undercity (5e)


Battle for the Undercity is a D&D 5th Edition adventure designed for a DM’s use in any Forgotten Realms™ campaign. It was designed and written by writer, editor, and developer Monica Valentinelli (Firefly RPG, Vampire: the Masquerade 20th Anniversary Edition, and Hunter the Vigil 2nd Edition lines), with rules and editing by developer, writer, and editor Scott Holden (Scarred Lands RPG, Ravenloft RPG, EverQuest RPG, and EVE Online).

Battle for the Undercity takes place underground in a section of a major city. The party will navigate sewers, worked tunnels, forgotten crypts, and freshly dug passageways to fend off adversaries in order to rescue hostages and return them safely to the surface unharmed. Can your party emerge victorious and save the day?

In this adventure you will find:

* Adventure background and hooks

* Map to the Undercity

* Detailed location guide

* Suggestions to increase and decrease the Challenge Rating

* Advice to customize the adventure to your party

* New! Crimson Coins thieves' faction and characters

* New! Ten Legs tribe, Goblin Beast-Master, and Beast-Rider monster variants

* New! Corrupted Shield-Guardian monster variant

* New! Ancient Revenant monster variant

This adventure includes three, separate three-to-four hour long missions that can be run in any order, depending upon the needs and composition of your party members. While this was designed as an adventure module for 7th- to 9th-level characters to be run in the recommended timeframe, you will find notes to adjust the missions to increase or decrease their difficulty and length.

I was just reading through this today, and I was curious why the recommended party level is 8 (or 7-9 as it also says). It doesn't seem like the monsters, traps, etc. would be a challenge for a party of that level. Not sure if I'm missing something (I know there are tips for increasing the difficulty, but I'd assume you wouldn't need to do that for a level 8 party).

While the map is cool, I'd have loved for a version of the map that didn't include the icons.

Can't wait to run this! Wish there was an unmarked map, but I should be able to make it work on Roll 20 without too much trouble. Thank you!

Adding this to my wish list. Looking to have my group start with some fresh, level 1 characters, so this is higher level than what I need at the moment. But, sounds interesting.

Robert - Appreciate your point and its intent to help police the DMs Guild community from abuses.
We're going to be issuing an update to the Community Content Agreement today or Monday to update that section c and clarify the usage of stock art in DMs Guild products. This author's use is/will be permitted and they discussed their usage of stock art with us in advance of their release.

Rules Edition(s)
Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
