The Saint’s Tomb by Sayeth

This game is a hybrid of a choose-your-own adventure type computer game and a pen-and-paper roleplaying game. It is compatible with the fifth edition of the most popular roleplaying game in the world (you know the one).  To play this game, you’ll need a 1st level character  for 5e. You can create one using the free character creation feature at DnD Beyond (opens in new tab), or by using level 1 pre-generated characters. You will need to have this character sheet either printed out or open in a separate browser tab. You will keep track of your character’s hit points, spells, and inventory on your character sheet, and keep track of enemies using your own scratch paper. The game will play GM and all enemies.
For a Spanish-language translation of this game, see La Cripta Sagrada. To download this game and play offline, visit DriveThruRPG .  A version of this game with extended player controls is available at Artemis Games.
You can continue the adventure with A Miner Problem or fight one-on-one at multiple different levels with 5e Arena.
