The amount of damage you heal from using Dark Arts on this ability will never amount to more than the amount of damage you will negate from using it on Dark Passenger or Dark Dance. In other words, there is no scenario where the mana you spend on this skill healing yourself will ever be more efficient had you spent it on the other two. For the record, using Dark Arts on either of the two aforementioned abilities also amounts to less total mana spent.
I use it in dungeons unbuffed as a ranged pull, or when mobs are grouped to heal myself & deal AoE damage while Blood Price is up. This allows the healer to DPS more.

I also use it in A1S against Faust to heal myself as his stacks get higher. I tank both Faust & the adds so there's no issue with MP & healers can appreciate watching my HP take jumps to full.

I also use it in A2S. I use it once in Wave 2 for a quick heal when I'm pulling hate on all unstunned goblins, including the Hardmind. I use it 2-3 times in Wave 8 to heal back damage taken from Jagd while doing damage to the entire Goblin pack, helps make up for that lack of shield. I only use Power Slash combo two times in A2S & use Blood Price/Weapon often, so mp is rarely an issue for me.

Dark Passenger is on a 30 second timer and cannot be spammed with Dark Arts. DA+Dark Dance is mildly useful in dungeons, but overall a waste if your intention is to do damage & not run out of mp.
