Trash pulls:

Unmend one of the mobs. Use Unleash once (especially if you get an Unmend proc) just to secure starting aggro. Pop Blood Price and use Dark Arts + Abyssal Drain on the group until you run out or get low on mp. Use Carve and Split or Syphon Strike to regain some MP, popping any cooldowns you might need in the process. Once the group thins out, you can switch to single targeting with Syphon Strike > Souleater combo.


The self heal skills you heard about are those: Abyssal Drain and Souleater. Luckily, they still return 100% damage dealt as HP, even though the tooltip was changed to say "a portion of" and datamining suggested it would only be 10%.

For single pulls, you just want to Power Slash combo and then Dark Arts the last one. Then you can pretty much perpetually Souleater combo, using DA on Souleater most of the time. You can even mix in DA on Syphon Strike or Carve and Split (though you can save C&S for emergency mp too if you want). Pop Rampart and Shadow Wall as necessary. I haven't gotten any of the 62+ abilities, so I can't speak from experience on those, but they seem pretty straightforward.
