What Rolegend does differently

Keystone Engine is a game engine, built apart from the AI. It handles the dice and the game state. Every roll, modifier, hit point, condition, spell slot and item is settled before ROWAN writes a word, and ROWAN gets on with the story. ROWAN cannot change a number or roll again. When your character acts, the game hands you the die to roll, and Keystone Engine adds the modifiers from your sheet.

Play with friends or solo. A paid host seats up to 6 players at one table, the host included, and friends on the free plan can join. Each player plays their own character. When everyone is online you can play live, and the table updates every few seconds. When they are not, play async play-by-post and drop in whenever you want. In a fight each player acts on their character's turn, and an email says when the table waits for you. Alone, the paid party holds up to 6 characters that you play yourself, and the Game Master plays the companions who join you on the road; the free plan is a single character. The host picks the language that the Game Master narrates in, its tone and the length of its replies.
Rolegend's Virtual Tabletop puts a fight on a battle map, with a token for every hero and every enemy, and you drag yours to move. Keystone Engine enforces movement, difficult terrain, cover, line of sight, opportunity attacks, flanking, weapon ranges and light there, and the fog of war hides anything your character cannot see. Every player at the table moves on the same map. Between fights, the map shows the region and the lay of the land in each place. A quick scuffle can also stay in the story, with no map at all.
On the paid plan, any Game Master turn can be read aloud, with a narrator voice and a voice of its own for each character who speaks, and you can turn on reading each new reply aloud. One click paints a scene image for a turn or a portrait of your character. You can dictate your own turn on either plan, in a browser with speech recognition (Chrome, Edge and Safari).
Async play-by-post with no daily cap on responses: write a turn, close the tab, come back next week.
