As everyone else has said gear, interupts, interupts, interupts. However, I would like to add a guestion to all about this. I have 4 interupts, maybe 3 when I fought him but reguardless how fast does your interupts recharge? There are some mobs that use special ability after special ability and my interupts can't charge fast enough, plus some do not work on some mobs. Is your skill tree and basic stats the factor here? Jedi Sentinal here, just wondering?
