Automated Version If you want to use an automated Version of this, check out: www.rollruin.com What is this? •This generator creates system-neutral classic-style dungeons and caves for any fantasy TTRPG. How to use this? A step by step guide •Start by choosing to either create a cave or dungeon (both may lead to the other later). Go to the corresponding page and tables: p.2 & tables A for dungeons, p.5 & tables D for caves. •Start by rolling to determine the entrance type ( A1 & D1 ). Roll the type of dungeon/cave if you want a more specific theme for the whole structure ( A2 & D2 ). •Afterwards roll the first room of the first level ( A3 & D3 ) and roll for the stocking of the first room ( B2 & E2 ). Additionally roll for dungeons the door type ( B5 ) and for caves stone type ( E5 ) of the first room. •Each square is 10x10 feet. Each opening, marked by arrows, leads to a new room which has to be approached and explored to reveal its form and contents. •To create a new room at an opening, roll sequentially 4D6: •The first D6 determines if the room is a corridor or chamber and door for dungeons ( B1 & C1 ), or if it’s a tunnel or cave and the type of offset between both rooms for caves ( E1 & F1 ). •The second and third D6 determine the shape of the according room type ( B1,C1,E1 & F1). Rotate the rooms to fit the map layout and ensure proper connections to adjacent rooms. Create as many loops as possible (Jaquaysing a dungeon). If a new room shape overlaps an existing room, adjust the new room‘s shape to fit the space and connect room openings if existent. •The fourth D6 determines the stocking / content of room ( B2,C2,E2 & F2). •Additional rolls of various dice may be needed afterwards to further determine specific room features, monsters, treasures and other elements. These may also require extra rolls to create even more specific and unique elements. •Tables are stated to help with cross-referencing.
