Modos RPG

What the heck is going on with Modos RPG?

Hey! Thanks for stopping in. If it looks like I took the summer off, well, that’s only partially true. Since Modos 1.4 is the most stable version to-date, I’m letting it stand on its own for a while.

However, that doesn’t mean that the web has stopped growing. I have two modules in the works: one is a Metroid rules module, for running PCs through alien environments and blowing things up, and the larger project is a Gauntlet conversion called Dark Amulet. The latter is designed to be a fast-play-dungeon-crawl, with treasure, danger, and some spontaneous elements. Since Metroid is smaller and getting more attention right now, you can expect to see that first. Dark Amulet is not a rules overhaul, but contains enough changes to create a slightly different feel of play (like being GM-less).

Look for the Metroid module by the end of August, and Dark Amulet by September or, eerily enough, Halloween!

1.4 Implemented

Good news for those of you who haven’t yet dropped your Modos RPG rules into Excel: the Rules Catalog on this site now has the 1.4 rules modded into the 1.3 rules.

Merry Christmas!

For those of you who wanted a smoother-running game to play, rules update 1.4 is now available. Follow the link from the Wiki page, happy gaming, and happy holidays!


This year, I’m thankful to have released the third version of my favorite roleplaying game! But as these things come and go, I have sad news: version 1.3 is about to expire.

In its place: version 1.4! This is represented by my…second official rules module, and just like version 1.3, it will be free to all. I realize that digital information doesn’t look so hot under the Christmas tree, but I’m expecting to have the rules module available by Christmas.

Happy gaming!

Update Update

New sections on player agency, how the dice work, and awarding hero points. And that’s just the GM chapter…

I’m happy to say that the Counters section is being superseded by a new initiative chart that will make combat a breeze. Of course, the initiative chart will require a sheet of paper or window, where the counters did not.

Upcoming rules patch

The game’s getting a workover, but gameplay won’t change much. You will hopefully feel a general smoothing of the bumps. There will also be some focus on increasing the details used in storytelling, and including players in that process. So, more imagination. And a handful of demos to help you get a better feel for how things work, before you start playing with your group.

What spell subsystem?

The streamlining continues. The cover rules for spells were bulky and confusing. I tossed them out. Now, what a spell can hit is determined by its range.

A Close range spell can hit just about anything to which it has a direct, unobstructed line: from offensive posture to offensive posture. "+ 4 difficulty.

A Short range spell can hit targets further away, or those with a little bit of cover. Read: offensive or defensive enemies. 0 difficulty.

A Medium range spell can hit targets who are out of combat, or those who would otherwise be very difficult to hit. -4 difficulty.

A Long range spell can affect just about anything – see Rule Zero for clarification. -8 difficulty.

Playtest update

Lots of revisions, recommendations, and revolutions are waiting for attention. I’m not quite ready to put out another playtest version, but I think an update packet is very likely. Visit here to get your 2 gold pieces in:

Perk evolution

I’ve been looking at levels today, which led to level points (probably becoming an optional rule), which led to perks, which are almost equivalent to level points if you consider that the perk substitution rule allows you to buy anything with a perk.

Well, as stated over a year ago, one goal of the game is simplicity. Which makes level points, perk substitution, and optional rules look pretty silly. So now I’m looking at something like this:

Attribute substitution perk:
With this perk you may increase an attribute score by 1.

Skill substitution perk:
With this perk you may add one skill point to any skill.

With these, you spend your perk (the one that you get with each level) on a perk, and that perk becomes the substitution. There’s no overlap complication when it comes to counting level points, because there are no level points. Sure, these perks can make attributes or skills look more inflated than perks (mostly when designing and balancing monsters), but it means that the total number of perks always equals character level.

Minimum Casting Difficulty

I’m taking a look at the minimum casting difficulty rule. 11 feels too high. I’d like to try a minimum of 1 instead, so that spells that are difficult to cast or spells cast under difficult conditions can have contests under 1 that prevent them from occurring. But do you really want to get caught in a magical spider web by a caster whose contest was only 4?

Bad example, because your parry contest to free yourself would be super easy. But you know what I mean…
