Ask a rules question in your campaign and the Game Master Assistant replies in plain language, with references when possible. Adding books from the Marketplace into your campaign gives the Assistant access to them and it will start using them to answer your questions on rules and lore.
More fun at the table, less fuss around it
The tavern falls quiet. You spent all week on this villain: the scarred voice, the secret letter, the slow reveal in the final act. Your players have other plans. They have just set fire to the only bridge out of town, the paladin is deep in an argument with a goat, and the rogue has quietly pocketed the letter that was supposed to unravel everything. Somewhere across the river, your villain stands alone in the rain, waiting for an entrance that will never come. The bard leans back, grinning. Four faces turn to you.
