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.

You are heroes! Attacks. Just. Hit. 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 through 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.
