I'm afraid not, the Dark Curse skill is only available on three swords, the Dark Mutineer, Treachery's End, And the Behemoth blade. It's also a skill on one un-released sword, the Shadow Cutlass.

Although, this sword does have the Shock Sweep ability, which is exclusive ONLY to this sword and the Emerald Curse.
