100 Staircases to Find in a Dungeon, 100 Encounters for a Fantasy Desert (3Deep) and 100 Notes and Letters to Find on Urth II are now available to buy from DriveThruRPG.
Dungeons have staircases, of whatever sort, to connect levels, or parts of levels, together. 100 Staircases to Find in a Dungeon has staircases that a GM can drop in to make the area more interesting. They can be used as colour, hazards or potential adventure hooks.
Deserts can be mysterious and dangerous places and 100 Encounters for a Fantasy Desert (3Deep) has 100 encounters that characters could have. They can be used to enliven a desert journey.
Characters may come across notes and letters, whether searching a room or a body, and 100 Notes and Letters to Find on Urth II has 100 such for them to find. They may or may not be relevant to anything.
