So I've been using (and loving the play style of) Dark Knight the past few days, having been a PLD for the past few months, it's a breath of fresh, lovely, dark and wrist slitting air.

I just have a few bugbears with it and wanted to know what other people thought, mainly around how abilities are worded.

So on your main enmity combo HS > SS > PS, the wording on Power Slash tool-tip states:

Delivers an attack with a potency of 100.
Additional Effect: Increased enmity
Combo Action: Spinning Slash
Combo Potency: 300

But then, once Dark Arts is obtained, the tool-tip adds:

Dark Arts Combo Effect: Increased enmity.

It looks like Dark Arts adds an effect the skill already has, unless I'm reading it wrong, does it do increased enmity twice? Or does it mean I can use Dark Arts and Power Slash without having to combo into it with HS > SS? Seems very confusing.
