Yes.
Important observations:
1) Have an instant Spell that you can cast with low mana (IE, Arcane Shot r1). He does a nasty Mana Burn that will hit you most of the time, but it does next to no damage when you're OOM.
2) You have to get him at 50% BEFORE getting to Shatt, or else A'dal will 1-shot him even if he becomes immortal at 50%.
3) A'dal WON'T get your aggro. Unless you have a threat dump, you WILL die once you get to him.
