Infinitely scalable for any setting or genre, the B/X Options: Class Builder lets you create new (or modify existing) classes guaranteed to match the level progression rates of the canon.

Contained herein is everything you need to create perfectly balanced classes for BX-style RPGs, plus:

  • 30 variants of the existing classes
  • 13 new sub-classes
  • Optional d6 skill system
  • A d6 conversion of  the classic Thief skills
  • Optional spell failure guidelines
  • Animal totems and abilities
  • New armour and weapons
  • High-level options for advancing classes beyond 14th level

Could this be used to make humanoid classes like Orcs of Thar? Goblins, Orcs, Bugbears, Ogre, etc.

Hi Chad,

Yes, you could figure out XP based on humanoid abilities and create Level Progression tables for advancement. However, you'd have to decide how you want to handle multiple HD at first level - the Class Builder doesn't deal with negative XP as used in Orcs of Thar or the Creature Crucible series.

Just purchased and pleased. However, I would have really liked a detailed worksheet breakdown of the additional variant and sub-classes. For example, what was the cost breakdown for the shaman and beast-talked class; specifically, what is the xp value for the animal companion ability? I noticed such worksheets were requested at the forums, but still no such resource.

Hi Phillip,

Thanks for your support, though I'm sorry to disappoint with the lack of worksheets for all the new classes.

As noted below, space considerations prevented their inclusion, but since it's come up a few times I have a cunning plan: In the short term, I'll post the additional worksheets to the Welsh Piper website (sometime this winter). In the long term, I may add them as an appendix to the next printing OR (preferably) create an online class-building tool that includes the new classes and variants as "templates" for cost analysis and tweaking.

More to come on this front - in the meantime, thanks again for your support!

Thanks again for your support!

Thanks for the quick reply! I understand the need for space considerations, but it's definitely something that I feel would enhance the product in the future. That would be great if it was posted to your website (a site, by the way, that I have referred my B/X group to before). That way, I could better understand how you applied xp costs for things like animal companions, familiar territory/home terrain, and some other unique abilities. Maybe that's something I could ask in your forums? Again, great product with good value. Peace.

When the worksheets are complete, I'll announce on the site forums and both the B/X and OSE Facebook groups. I'm working on the next BX Options book now, so I want to clarify that this won't happen for a couple months.

Updating the 3rd printing will take longer - I also want to add a section on creating new abilities, and with extra pages comes a new cover spec, proofs, etc. I don't have a target date for that yet, but it's on my list.

Thanks again for the kind words and support. Cheers!

While the sample file has 17 pages, what it doesn't show is if there are worksheets for all of the new classes. For instance, does the Crusader's Clerical Spell casting cost 500 xp or fewer?

Worksheets are provided only for the "core" classes as proof of concept. They are not included for new classes to conserve space. If there's interest, I may provide these via spreadsheet or as an appendix in the next edition. In answer to your question, Crusaders have a maximum divine spell level of 3, for a cost of 300XP.

Hi Alejo - I'm awaiting receipt of the print proofs from DTRPG now, so the POD versions should be available before the end of August.

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.
