Here at Nero Las Vegas we are using the 9th edition ruleset with a few small modifications.
1. Laugh Effect exists and will cause uncontrolled laughter for the duration of 5 minutes with no in game skills and you can not run.
2. Dismemberment is still allowed to be role-played.
3. Arcane delivered Charm Effects that would normally expire after only 5 minutes have the duration changed to Line of Sight or 5 min whichever is longer.
