Event Code 2,707,187

COSCON is a three-day convention run by the Circle of Swords Gaming Guild, and is one of our two highest-attendance conventions of the year. It usually features a multi-table special on the Saturday of the convention. This year, we’re planning on running PFS1 3-00 Blood Under Absalom as our special event, as well as SFS 1-98 Into the Perplexity and a Christmas-themed one-shot Cracked! written by our very own Idaho!

GM Rewards

For our currently supported campaigns, Pathfinder Society 2nd Edition and Starfinder Society, rewards will come in the form of enhanced Achievement Point earnings–you’ll earn more for playing and you’ll earn even more for GMing!

For Pathfinder Society 1st Edition, you’ll be able to earn a GM boon. This boon will unlock a race for play, although we don’t yet know which race will be unlocked.

The Circle of Swords organization provides free admission for GMs who run three tables (of any system, not just Pathfinder or Starfinder). If you GM one or two tables, they provide you with credit usable with the vendors.


We need your help! We want to have a dedicated volunteer at the Headquarters (HQ) table every slot. The responsibilities are pretty simple, but someone needs to do them, and that could be you! You would get GM-equivalent rewards for doing helping out.

Please email Alex if you want to help!
