  • Ranged Aoe; 15y, unlike Unleash; can be used if needed to grab 2+ mobs from a distance.
Unleash:
  • Costs less than Abyssal Drain but only has 100 potency so generates less enmity;
  • Unmend can proc a free one of these, sometimes it's MP efficient to Unmend 2 things to increase chance of getting that free one.
  • DOESN'T interrupt combos, unlike Abyssal Drain.
  • Costs less MP so when you're running low on MP, it's a safer option than Abyssal Drain to stop you from losing Darkness.
  • Centered around you, but fair amount of lag. If you're used to using Flash, this won't pose a problem for you.

Basically, if you have a bunch of enemies with you, Blood Price will make it so you won't have to worry about MP, so use Abyssal Drain. Better enmity and better DPS output. Once you hit around ~30% MP, you stop using skills that consume MP until your bar is full or close to full.

Sole Survivor, you just want to throw it on a mob that's about to die. Don't wait too late, as it can eat the cool down without applying the effect. Put it on too soon and the mob might not die before Sole Survivor fades off. If you need to, make a macro to let your party know about it and prioritize the kill.
