After unlocking Megalo Syuuto or finding the Nightsword on top of Mount Moonspell, players must find a particular mask to transform into Muramasa.
A dangerous and cursed weapon, the Night Sword is a powerful blade introduced in Vampire Survivors’ Legacy of the Moonspell DLC. Those who wield this sword will viciously slash nearby enemies with a series of slashes and can retaliate by attacking six times in an AoE around the user. Additionally, there is a small chance that the Nightsword will draw consumable blood from its enemies that can heal its wielder. This possibility is based on the luck of the player character, as those with higher luck will be able to produce more healing heart drops from slain enemies.
To obtain the Nightsword in Vampire Survivors, players must head to the northern peaks of Mount Moonspell, high above the dojo where Miang Moonspell’s coffin is located. Along the way, adventurers will encounter various enemies, including trolls living in the mountain caves. A shrine can be found near the top of Mount Moonspell, guarded by a massive skeleton stuck in the dirt. To reach this shrine, players must follow the dirt path marked with torii gates and avoid entering the troll caves along the main path.
How to Unlock the Nightsword Slot in Vampire Survivors
According to YouTuber Hold To Reset, players don’t need to kill the Skeleton Guarding the Sword of Night in Vampire Survivors. All they need to do is pick it up and walk away to permanently unlock it for future runs. Coming back down the mountain should be a little easier once adventurers acquire this deadly blade. Alternatively, players can obtain the Nightsword indirectly by unlocking Megalo Syuuto Moonspell, Syuuto’s strongest form. Megalo Syuuto naturally has higher inherent stats than Syuuto and uses the Nightsword as his starting weapon in Vampire Survivors. For reference, players can unlock Syuuto by leveling up Four Seasons, and Megalo Syuuto becomes available once players kill 100,000 enemies in a single run with Syuuto.
Night Sword’s evolution in Vampire Survivors is Muramasa, which has much higher base damage and a higher chance to drain the hearts of enemies killed. Additionally, this demonic blade can deal critical hits with deadly combo finishers. However, Muramasa’s supernatural power comes at the cost of a permanent HP drain from its user, which can be countered if players have a high chance for self-healing. To evolve the Nightsword into Muramasa in Vampire Survivors, players must acquire and max level the Stone Mask. An accessible Stone Mask can be found through the forests east of the Nightsword Shrine on Mount Moonspell. For convenience, using the Mad Groove Arcana can bring the mask directly to the player character’s position.
