Hey folks,
Have just helped another group of adventurers get through prommies without incident, so I thought I would just add a simple but efficient way to NOT black screen.
Nothing is more frustrating than a black screen in Prommy, even worse if there's no GM to help, but the answer is very simple.
After defeating the Memory Receptacle, kill all the strays, then have an order for players to enter the portal.
Let the first person go and have them send a "/" when they have arrived, then the next player enter.
Simple, but works every time and saves frustration and time..
