"Heal" should work. "Greater Restoration" should work. Even better, an in-game plot solution should absolutely, 100% work. Like have one of Auntie Ethel's cursed bottles have some obscure name that will get rid of the effect so ppl won't have to wait until level 9 when they have access to the previous spells. A Pali breaks their oath and they get arguably more powerful. There are numerous other pretty major effects that only last until you rest, and this one, from a Hag, which you meet at low level can literally ruin the entire concept of your character. And yes, if you are playing a scout it absolutely tanks your character, if not from a game stand point since you can always use Astarian or respec someone else into the main scout, but you probably made a character focused on finding things bc that is what you wanted to play. I mean heck, a simple remove curse gets rid of the Necromancy of Thay debuff!?! It gets rid of Celestial debuffs. It get's rid of Djinn debuffs. But that 5th level Hag? Oh no no no, that's a bridge too far. A Hag who doesn't come close to keeping her side of the bargain. If they really wanted to be strict they could let it be something you needed, say either Rafael or an encounter with a/nother Hag or Fey creature to get rid of. Maybe give a Pixie the option of either giving you Shadow Curse immunity or _"Bringing the light"_ back to your eye since, though quite the pain, torches do do the job, and you can get a moon lantern at other places in the game save from the Drider.

I quit the playthrough with my cursed eye Ranger after being max level for over 150 hours. The two things in conjunction were just too much and I simply was not enjoying myself at all anymore. 200 hours with the curse was just a bridge too far. Kinda funny bc this character would be fine with the curse and it would not affect them at all. Literally. They fail perception checks almost as often as the Ranger did. Of course the cursed Ranger had two items that were supposed to give them advantage to perception checks which didn't appear to do much. A bit silly when a Tempest Cleric does in fact make a better scout than my 18 Wisdom/18 Dex (bracers) level 12 Gloomstalker. So many options in regards to how to handle _fixing_ this effect, but Larian seems to really be sticking to their guns here. It's too bad more people don't play scout classes, and I notice the ones who do tend to play them are far less inclined to do something that effects their character cosmetically. They are also far more likely to reload if something like this happens and not try to play through it, assuming it either "A." won't be that bad or *B.* assume, and naturally so, that there will eventually be a cure/mitigation for it. What's next, are they going to have an Efritti who burns out Bard vocal chords and scars their fingers so they can no longer play instruments? This debuff is that serious for the people playing certain concepts, but wtv. I know that I'll probably never play a Larian game, as great as they have been, without save scumming. Trying to play with something like this just to figure out 100 hours later that there is not going to be a solution makes taking that chance way too risky. I'll go back 5 real life, maybe even 10, but not 20 or 30, never mind 100+.
