Strahd von Zarovich
Among the monsters in D&D canon, Strahd von Zarovich is one of the most feared. His stat block and features, however, do not live up to his threatening mystique. In some ways, this should be expected: Strahd’s fearsomeness comes not from his game statistics, but from his strategic and tactical abilities. You can play Strahd’s stat block as written and have little problem TPKing a party of four or five 10th-level players.
This guide focuses on using Strahd’s existing stat block alongside effective strategies to make the final encounter with him unforgettable. The main mechanical adjustment I suggest is to expand Strahd’s spell list, which you can alter based on Strahd’s temperament and situation.
