The Cursed Seafang Blade is a blade that was released at the time Raven's Cove came out for players to test. It was the first Cursed Blade to be seen in POTCO and the only to be unlocked by a redeem code. The sword is covered in barnacles, as if it's been sitting on the bottom of the ocean for a while. The weapon skill Cursed Thunder uses 80 voodoo, and does a fair amount of damage, around 300 damage points.
In a way, unfortunately, you can't get the Black Spot from wielding this blade.
This Cursed Blade was only obtainable by the redeem code seafang.
Note: This code has expired and the blade is no longer avaliable.
