Wish Consequences: Become Powerful Vampire
A player has gotten a Wish from a previous campaign. They are starting an upscale version of Curse of Strahd as level 10 players.
He has been contemplating using his Wish to “become the most powerful vampire ever.”
How would you rule something like using the Wish to do something like that, or even something as simple as leveling up more quickly? Appreciate the feedback
