Hey guys!

So i've already beaten this bad boy a few times on my PLD but always the other PLD insist on MT and i always end up having to stunlock those annoying adds and so far we managed. but i'm not satisfied with my results, maybe its my team not killing them fast enough? But often they get one or two skills off which shouldn't happen.

can anyone help me out here?

i usually wait untill the mob gets to around 80% of HP then i stun them, Last 6 seconds. When that hits 1 i wait one more second then stun him for another 3.
Then my stun only lasts 1 second? And from that point on he will be able to cast dread stuff, Or do i just do it wrong?
