The Cursed Sword is a sword-type meleeweapon that has extremely high DPS, constant critical hits and a fast swing rate, but makes the player cursed as long as it is equipped.
Details[]
Special Effects:
Curses the player while it is carried, killing the player immediately upon taking damage.
It is still possible to get curses from other sources, in which case they operate independently from the sword itself.
The curse of the sword alone is lifted if the player removes it from their inventory. However, it is impossible to lift it any other way.
Thus, the Cursed Sword is not subject to mutations like Alienation or Acceptance and their effects.
"You deal +300% damage but you can't use any other item."
Notes[]
There is an achievement associated with this weapon called "I like to live dangerously...", which is achieved by completing a run with the sword in possession.
The weapon's curse mechanic remains active even if it is merely held in the backpack (and therefore technically not "equipped" in the usual sense). The curse effect can only be escaped by dropping the weapon entirely.
There is a bug involving holding this item in the backpack. Unless you drop it by holding interact, the curse will not be removed; even if you swap it to an active slot, and then drop it by swapping to another weapon.
Unlike a curse from a cursed chest, equipping it does not prevent the player from using Homunculus Rune and does not trigger the crit damage condition of Spite Sword.
Ygdar Orus Li Ox will not be triggered when killed with this weapon in your inventory.
the Damned aspect makes the drawback for the sword not trigger, making the sword not kill you in one hit making it really overpowered
cursed as long as it is equipped.
