Solar Blades & Cosmic Spells - NPCs in Action

Artwork by Louis Glanzman
One of the most common questions people ask me about Sharp Swords & Sinister Spells is how to handle NPCs actions, either when they are acting against PCs, against themselves or alone.

So in Solar Blades & Cosmic Spells, I decided to provide some guidelines for this.

NPCs in Action


Most of the tests in this game are focused on the player character's capabilities, as they are the main characters of the story being created during the game. It’s also much easier for the Overlord to rely on the character’s statistic than to create detailed statistics for every NPC and opponent the players might run into.

Thus, if a NPC is attempting an action against a player character, he rolls a d20 and needs to obtain a result higher than the pertinent Attribute score of said character. Note that the Powerful Opponent rule applies here, adding the difference between the NPC’s HD and the character’s Level.

Spotting a nearby ruins, Kaylia runs towards it and closes its stout metal door behind her. The giant worm was soon upon the door, pulling his weight over it. The Overlord rolls a d20 + 4 (since the creature has 5 HD and Kaylia is a 1st Level character) and gets a total of 13, which is the exact score of her Physique. Even though the worm is incredible strong, Kaylia manages to keep the door close for sufficient time for it to lose interest.

However, there may be times when the Overlord wants highlight the ability or proficient of some NPCs and opponents, and it is important to assign an Attribute score for them. A practical way to do this is assuming they have an Attribute score of 10 plus their HD, and giving them a Positive Die for tasks they should be good at or a Negative Die on tests they shouldn’t be very good with.

Inside the ruins, Kaylia found a terminal still functioning. Hoping to find any information that could lead her to find a way out of this planet. However since she activated her Complication, the Overlord decides it’s time to introduce her Evil Twin Sister in the adventure. He thinks about it and want to make her the reason all of this happened. She sabotaged Kaylia’s starship and is even interfering with her ability to search data in the terminal. Having 3 HD, her assumed Attribute score is 13, so the Overlord rolls a d20 and gets 12. Now, Kaylia’s has to roll higher than that on her Intellect test to actually get some useful information on the computer!

Finally, when a NPC acts against another NPC, they both roll a d20 and add their HD, comparing the results. The one with the higher result wins the dispute and gets to do what he wants. This is used especially when player characters have retainers and they are used to battle other NPCs and opponents.

Managing to use the terminal, Kaylia calls for help, sending a message to the stars. As guild of mercenaries owes her a favor and they send a small retinue of soldiers to aid her. As they arrive, they are received by Kaylia’s sister firing a machine gun at them. Both parties roll a d20, adding their HD. If the mercenaries win, they dodge the rain of bullets, if she wins, she will inflict damage on their vehicle.

My RPG Zine Trilogy is on Kickstarter!

 I can't believe I didn't post about it here! The Dead are Coming, Screams Amongst the Stars and Running Out of Time are on Kickstarter right now! These are 3 complete games, made using the system of Electric Bastionland and Mausritter as the basis (and with some modifications to fit my vision for each of them). As with my games, they all come filled with many tools and tables to generate gaming content, adventures, locations, NPCs and much more. They are compact, easy to use, and equipped to provide you with years of entertainment! Here's a brief description of each of the games. The Dead Are Coming The first of them is called The Dead Are Coming, a minimalist, OSR style RPG about survival in a post-apocalyptic world where the dead have risen and other survivors can be much worse than the undead. Characters in this game are common people who have been struggling to survive, find their loved ones, keep them safe and just trying to keep living. They all carry resources like...

How to never describe a dungeon!

Artwork by Luigi Castellani I've heard it a thousand times. You probably heard it too. Some people , I don't know why, say that dungeons , especially large ones, are boring . The endless repetitions of rooms and corridors and having to choose to go left, right, north or south depresses them. I don't know why. Actually, I do know why. Because they don't really know how to run a dungeon in play. It seems easy, effortless. Just say what's in the room the PCs are in and where the passages going out of it go. But it's not. They get bored with the "you get to a intersection and there is a door to the north and two passages, one going east and one going west" because that's a terrible way of describing a dungeon environment and gives nothing really useful to the players to choose from. You never describe a dungeon like that . There's a lot more going on that we can initially see. A good referee will take all the context of what the dungeon w...

Dark Streets & Darker Secrets - Complete Game Text

November was NaGaDeMon (National Game Design Month), and I decided to create an Action Horror RPG using my system (updated with all the modifications of Solar Blades & Cosmic Spells). Inspired by Buffy the Vampire Slayer, Supernatural, X-Files, The Chilling Tales of Sabrina, Grimm and many more TV Shows, comics and books, I quickly worte Dark Streets & Darker Secrets . It is written in a very direct and simple way, similar to Sharp Swords & Sinister Spells originally was, but with uodated rules and a lot of tools and tables to assist the Referee in creating adventures, NPCs, locations, artifacts, monsters and much more. The book itself will eventually be release in partnership with Gallant Knight Games , but the text is already written and ready to be used, so I am sharing it here with you all! There is no official character sheet yet. I am working on it. But a simple Index Card will work just as well! So here it is:  https://drive.google.com/open?id=1QlFYafvxv...
