Had this conversation with someone who chose to no longer be at my table after meeting a blind NPC
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.
I think the real problem is that magic in D&D is so mundane that any problem can be "magicked away", be it healing a wound, curing diseases or exploding an enemy. That makes some situations only really plausible when it's explained as some stronger magic or "weird power" interfering with common magic.
It's a magical fantasy setting, I get it, but magic being so common and consequence free makes it a deus ex of whatever flimsy explanation you can imagine. "Why do disabled people exist in typical D&D?" Cue that meme of the cartoon's Dungeon Master "It's magic, I ain't gotta explain shit".
You can do it with limits, like having bigger wounds heal wrong if you try to heal them too fast (which is how broken bones are handled IRL, sometimes they must be re-broken to correct the healing process)
