Had this conversation with someone who chose to no longer be at my table after meeting a blind NPC
(files.catbox.moe)
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.
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.
And that's if you decide a spell that primarily exists to cure fairly rare conditions is common enough to fit in that category.
