Nimble is a fast, tactical (and 5e compatible), TTRPG. Your game nights are too precious to waste with slow or fiddly rules! Slay the slog using the best elements from the greatest RPGs around. Nimble empowers players and GMs with more interesting choices, less waiting around, and have more fun playing epic stories
Description
Nimble RPG is designed to prioritize speed, tactical decision-making, and reduced administrative tracking for both players and Game Masters. The system condenses character sheets and streamlines the action economy to prevent long waiting periods between player turns. Its primary design philosophy centers on accelerating combat encounters without sacrificing strategic depth, utilizing highly lethal weapon mechanics and dynamic monster behaviors. The game is offered both as a complete standalone system and as a modular "rules hack" booklet that can be integrated directly into an ongoing
campaign.
System Overview & Key Features
Fast Combat
Don’t waste your time rolling to see if you can deal damage, just roll your damage dice! You deal that much damage. Attacks miss on a 1, but rolling the maximum is an EXPLODING Critical Hit!
Exploding critical hits
Roll the die again and add it to the total. There is no limit to how many times this damage can stack, except your luck!
Instant Initiative
Get RIGHT into combat with Improved Initiative rules that get players immediately into combat in a way that serves the story without breaking up the flow.
Quick to prep
Nimble is quick to prep and easy to run. You've got enough going on while GMing—Mechanics are all designed to be easy to manage and track at the table. You can be ready to run an adventure in as little as 5 minutes! And there's no need to for new players to read though endless pages of rules, teach new players as you play.
Easy to balance
Easy Encounter Creation. No matter the size of your party—whether you play in a cozy group with just 1 or 2 heroes, or a huge group of 8 or more—Encounters are easy and intuitive to build and balance for just the right level of challenge you like. Craft massive scale combat encounters, down to legendary solo encounters.
Strategic Weapon System
A subtly DEEP weapon system that rewards thoughtful play. No more, “I guess I’ll pick the bigger one...” Every weapon is balanced to have interesting strengths & weaknesses in combat.
