d30-based Mechanics, Charts, and Tables to Support and Simplify the Role of the DM

The d30 DM Companion is an indispensable aid for any OSR DM that wants to keep on top of his game and ahead of his players. Whether stocking a dungeon or just struggling to keep up with players, this compilation of d30-based mechanics, charts, and tables will support and simplify the role of the DM/GM at the tabletop. Inside these 30-something pages you’ll find a host of d30-based resources for quickly creating characters and stocking dungeons.

While the majority of the charts and tables in the book are generic to dungeon settings, monster descriptions feature details for 1e and BX comparable games, including Oe D&D, 1e AD&D, BX D&D, Swords & Wizardry, OSRIC, and Labyrinth Lord.

The d30 DM Companion includes a host of d30-based resources, including:

• super-quick character generation for classed characters, 
including: attributes, motivations and equipment/inventory

• general dungeon features, embellishments, debris, and 
geological phenomena 

• 27,000 mold/slime variants and 27,000 mushroom variants

• monster encounters for levels 1-9 (270 listings)

• single d30 determination for ranges of "no. appearing"

• monster stats for over 175 monsters and 14 types/classes of humans/humanoids 

• 900 trap variants based on 6 trap categories 

• treasure hordes (by type) in fewer rolls

• 27,000 unique gem-based treasure items

• 27,000 treasure variants of magical weapons and armor

• 27,000 variants of scrolls, potions, wands, staves, and rods

• over 1.45 billion potion variants

• 60 new miscellaneous magic items

+ a master mapping key and a reproducible Dungeon Crawl Worksheet to assist DMs in mapping and stocking the rooms of their dungeons!

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.
