I was thinking about Darkness Blade. It could be the ability to use a certain demon blade, kind of like Elucidator, but more powerful. It would be a select few sword that have the essence of shadow forged into the blade, but you can't use the shadow portion until you have the skill. The skill would increase the power of an attack proportionate to the number of monsters you have killed since you equipped it, but the kill counter restarts as soon as you unequip the skill. Basically, you have to have it equipped constantly, but the equation for the additional damage would make it so it isn't op.
