It is a covenant specific ability similar to the Sunlight Spear's, or Darkmoon Blade's, damage buff with additional levels in the related covenant.

You can still use the Dark Hand but you only get 1 humanity at a time. It shouldn't matter unless you PvP though, in which case you might aswell be a Darkwraith if you want to steal humanity.
