Make your D&D games faster, better, more entertaining

Keep all your stat blocks and encounter notes online, on a single screen. Never slow down a combat encounter to shuffle through notes or to look up monster stat blocks in books.

Get 3 free e-books

Adventure Art #1 and #2

These 2 books feature over 25 NPCs and we've created stat blocks for all of them. Just use our public monster search tool and type the name of NPC from the books. You can copy these stat blocks to your account and have NPCs, complete with art and stats, in seconds.

This is a roleplaying game meant to be played as a one-shot session. Can't get your regular group together? Play Zombie Murder Mystery instead.

We give back to the community

Roleplaying games played an integral part in our lives and we believe it is a healthy, challenging hobby. We are committed to give back to the community. Every quarter Expy, Inc. will give 4% of its profits to a non-profit roleplaying club. If your school, college, municipal library, or youth center runs or is considering an RPG club, let us know. Send us the name of the RPG club and a short text about the projects you'd undertake with the funds, and you'll automatically enter the Giving Back program.
