The Coolest Combat System - A MOSAIC Strict System
A downloadable game
Inspiration is EVERYWHERE, but time isn’t.
The goal of this project is to provide an easy to use, universal combat system for game designers everywhere.
If you’re building a new TTRPG and need a combat system, take this one!*
Use all 6 dice in a polyhedral set, one for each of the major stats/events in the game.
A simple 4 stat, opposed d20 roll-off system with no list of modifiers, complex spells, or individual weapons to memorize.
Pick up and play format!
Designed in 45 minutes on a Game Jam episode of Beholder to No One podcast.
Update: We recently became aware of MOSAIC Strict rulesets, and TCCS certainly fits.
MOSAIC is a set of criteria that might be true of an RPG text:
- Modular
- Optional
- Short
- Attested
- Independent
- Coreless

Please link any products that you use this system in here so I can see the cool things folks make with it!
One of my submissions for the One-Page RPG Jam 2021 uses TCCS, check it out! The Battle Royale for the Megaverse Begins.
Very cool! Thank you so much for letting us know! Excited to take a look at Battle Royale
I made a character sheet for The Coolest Combat System: The Coolest Character Sheet
Thats so awesome! Thanks!
Creator update note:
I've now playtested this with up to 6 players.
A 4 player "battle royale" wrestling themed one shot ran for 2 hours flat, with a variety of archetypes. In 5e terms, at 50 HP that was 4 level 6 fighters.
The last player standing had about 12 HP left, and I was fairly free with Bonus awards to keep things fun.
In theory, if one slotted this into a storytelling system, you could do 1hr RP and have a 2 hr combat session. Or a smaller encounter to flip it.
It's very freeform, and lent itself to quick combat riff ideas. The players were engaged, and enjoyed getting to roll dice all night. The system lends itself to cinematic storytelling, with a GM helping guide the setting.
