This D&D is on an instance shard world and starts on the hour, so it is best to meet like 5-10 minutes before at spirit tree in the gnome stronghold.
The game runs only for 20 minutes and starts again on the next hour.
It is very simple game and you don't have to bring anything.
All you do is run in circles and catch moth.
It helps to pick a Protea flower and wield it during the game to attract more moth.
