Another player who was at the table during the incident sent me this meme after the problem player in question (they had a history) left the group chat.
Felt like sharing it here because I'm sure more people should keep this kind of thing in mind.
Lesser Restoration is free
If you've got someone willing to cast it for you for free, perhaps. But according to the PHB, most NPCs will charge far more than a typical peasant or low level adventurer could afford.
Hiring someone to cast a relatively common spell of 1st or 2nd level, such as Cure Wounds or Identify, is easy enough in a city or town, and might cost 10 to 50 gp (plus the cost of any expensive material components).
And that's if you decide a spell that primarily exists to cure fairly rare conditions is common enough to fit in that category.
