Elden Ring Nightreign saw a major meta shift after the release of an easily obtained relic packing a humongous damage buff tied to clearing Evergaol bosses. Players have now uncovered a considerably rare, exponentially stronger way to power up, and it's all thanks to one of the coveted Legendary weapons: the Grafted Blade Greatsword.
In Nightreign, Legendary weapons have special passive effects that often give sizable stat boosts. In the Grafted Greatsword's case, that stat boost scales based on how many enemies you kill, and there doesn't seem to be an upper limit on that scaling. The weapon passive reads: "Enhances all attributes upon defeating enemies. This effect accumulates."
