Mongoose Ultimate d20

In November 2023 we presented the all-new Mongoose Ultimate d20 Bundle featuring the Ultimate line of d20 System reference supplements from Mongoose Publishing.

In 2002-2005 Mongoose Publishing compiled 14 “Supplementary Rulebook” collections of third-party d20 System open content published under the Open Game License. Grouped by subject, these Ultimate volumes ranged in size from 48pp to 256pp, and gathered material from dozens of sources such as Alderac, Fantasy Flight, Green Ronin, Monte Cook, Mystic Eye, and Mongoose’s own Quintessential series. The production files for five of the compilations – Ultimate Prestige Classes Volume I, Feats, Arcane Spellbook, Monsters, and Magic Items – have been lost. This offer presented the nine surviving collections – more than 1,800 pages of d20 System reference material – as well as Mongoose’s Power Classes and two books of fantasy portraits suitable for character sheets.

There were twelve complete d20 System supplements in our Ultimate Collection (retail value $61) as DRM-free .PDF ebooks:

• Ultimate Character Concepts
• Ultimate Divine Spellbook
• Ultimate Equipment Guide Volume I, Volume II, and More Ultimate Equipment
• Ultimate Game Designer’s Companion
• Ultimate NPCs
• Ultimate Prestige Classes (this is Volume 2; Volume 1 has been lost)
• Ultimate Character Record Sheet
• Heroes of Fantasy, a compilation of Mongoose’s “Power Classes” series
• Character Portraits: Fantasy Heroes and Fantasy Heroines

[Note: Most of these .PDFs are pristine image scans of the original hardcopies with crystal-clear text. In three titles – Ultimate Character Concepts, Game Designer’s Companion, and Prestige Classes – the text is very light but readable and copiable, and scanned artwork is sometimes muddy.]
