  • If you pick a GM badge but are not signed up to run the required number of events, your badge will revert to the closest Player Online Pass type.

**Online Pre-Registration GM Pass Criteria/Restrictions

  • Must commit and be signed up for posted events on Warhorn when registration closes (i.e. no backouts after registration closes)
  • Pre-registration is required to ensure players can sign up for the event, (and for organized play events it gives coordinators time to get you mods to be prepared onsite)
  • If the number of GM events do not match the badge fee, you must pay the balance at the door onsite
  • As always, if you pay for any badge but end up GMing 3+ events onsite, we offer a badge refund of fees paid (and many thanks!)
  • As always, if events are scheduled/offered and the GM is ready to run but ultimately does not happen due to lack of player signups, there are no drawbacks or reg fees to repay
