I just want to start off by saying that all these books cost money. I am not trying to advertise for these books. If it is not allowed to post about other system neutral books I use with open legend then please close this topic.
Without further ado
Gurps:
I’m not talking about the core rule books; I’m talking about the tech books and the themed book like horror. These books are a really fun read and always give me ideas. Also on top of that they introduce me to things I otherwise would not be able to think of on my own.
Baby bestiary 1 and 2: These books bring the monsters of DnD in to cute babies you can take care of. You can use these for any system, it has specifics on how to raise and take care of these monsters. There are no stats just how to take care of the pets and how they act the phases of them growing up from baby to adult. Also the art work is amazing.
Return of the lazy dungeon master:
A great resource for DMs who want to prepare less but still have a full and fun game. I catch my self world building for hours on sections my players completely skipped because they didn’t like how hot the desert was completely missing out on the ancient library and the owl that guards it.
The lazy DMs work book:
This is a cool set of random tables but not really needed. Also the book comes with a few generic maps of places a party might visit with details for each room. In case your party decided to go in to a sewer you your self did not even know existed.
Fantastic locations / adventures by slyflourish:
A set of pretty basic adventures and cool places to visit. Each adventure is designed to be vague so you can add it in to any story you are making and add on to the adventure itself.
Adventurer’s almanac:
This book is just a big fantasy calendar that you can add to your world, Complete with fantasy made up holidays. Bosses and specific monsters that can show up in the specific seasons. This book has cool ideas in it.
How to write adventure modules that don’t suck:
Really fun read. Mostly just a collection of essays of people who write adventure modules with tips on world building and making adventures fun.
A Complete game master’s guide:
There are 3 of these books each on a different topic. This is pretty much the opposite of the lazy dungeon master. These books are about preparing to the max. I don’t know too much about these books I own them but got too intimidated by how complete these guide are. But I see value in them if you are that kind of person who loves prepping and world building.
The game masters apprentice:
This is a deck of cards and has many uses, and there is a deck for each theme from pirates to sci fy to zombies. You can replace your dice with these cards and they have key words to help give your brain ideas on the fly. Each card has a set of names in case you need a random name quickly. I have even seen a session where the group replaced the DM with this deck of cards and played a full session. I highly recommend checking out the youtube video to see all the uses these cards have.
Non player cards / book:
These cards are a bit pricey to get all of them. Looks like they just recently came out with a book at a much more reasonable price. These have been so useful when I run games. These cards just help you build NPCs or flesh out a player character with things like secrets and quirks. These cards really help me bring my characters to life.
Ending-
If you have any books or tools not mentioned here please add them. System neutral books are kind of hard to find So im always on the lookout for more. And I am hoping that one of these books or tools I posted about is interesting or useful for you. Open legend is the main system I play now and days so tools to help me run better games and be a better player in the system are always welcome.
