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.
In 5E, Lesser Restoration is free, so no one should really be blind, deaf, paralyzed, or poisoned. If they're missing a limb, though, Regenerate needs a vial of Holy Water that costs 25gp. For a commoner who makes 1sp a day, that's a lot.
Regenerate is also a 7th level spell - depending on the setting, the number of people capable of that kind of magic might not even exist outside of the confines of the party, or if they do, they're more preoccupied with the stuff worthy of NPCs with at least thirteen class levels.
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.
