The practice layer

One read a day keeps the leak away.

Every drill below is an in-game decision lifted straight from the books, with the rule and its source volume after you answer. The protocol resets at your midnight. Streaks live in your own browser; there's no account to make. When you want more than one rep, the field guide is the study hall: forty cards, word for word from the books.
