Question for the DRK's out there.

[Esp]

For me Abyssal Drain is your bread and butter for large AoE pulls. Gather them up, pop your Blood Price and spam it like no tomorrow. Course, this all depends on how many mobs are hitting you and how often, so you'll have to watch you MP guage and adjust accordingly. I think it was if there were more than 5 mobs, it would be worth it to DA it for the HP gain? Someone will correct me on that, I am sure

Another good use for it is when your pulling two separate pulls together, you can add in a single Abyssal Drain for that added enmity, since some DPS like to tag mobs on your way to either your next set, or your stopping point.

However, with each use be sure to keep a good eye on your MP and be sure you are still in that safe zone, otherwise, you end up starting a pull with very little MP xD
