Elden Ring Nightreign – as is required of any FromSoftware game – likes to punish its player, which is why you might unexpectedly become cursed by a demon, who then requires you to pay a heavy sum of Runes as penance. Or, as some fans have discovered, you can jump off a bridge and die.
After you're alerted to the fact that "a demon has cursed you" in Nightreign, a red spot on your map will guide you to a demonic merchant that will take either 15,000 of your Runes on Day 1 or 35,000 Runes on Day 2 to reverse its curse on your party. After this, he'll make a deal with you to grant you a powerful buff. But if you reject his rates, you can choose to battle him as a lesser version of the Libra Creature of Night boss.
