Hi DH community!
I’ve been doing the Vengeance DH Mage Tower for a bit and getting Kruul to about 11% before dying. I don’t know what I’m doing wrong. First Ann I do nothing. Second I soul barrier. Third I fiery and Ann, fourth I meta, fifth I last resort and try to kill. How is TW a dps check? I also am having issues with the portal adds and timing the sigil with the hp+ interupt because second wave and forward has it on cD Any tips please? 
Bro, this is the Warlock Section.
You should realistically not even get to 5 Annihilates. Take a look at your consumables, when you’re using them, and then your trinkets/weapon enchants. If you post on your DH, I can take a look. Wrong section of the forums, as Malacath said, but I did the tank one on another toon so I should be able to help you out nonetheless.
Oops LOL! I was viewing the DH forums when I typed it so not sure why it went here. Won’t let me delete it either
Create @player macros for sigil of silence and misery and alternate them. You need cheat death, not soul barrier.
A cheat death trinket can help. I got the one from lfr raiding in legion. The Haft. Also spirit bomb is a must. Save 3-4 soul frags to use on the ghosts as soon as you suck them in to variss. They die instantly after a sigil.
You need 3-4 healing orbs up going in to kruul. Not sure after nerf but I definitely needed them.
Last, focus macros help for interrupts.
If you have last resort then I assume you mean fel devestation. Fiery brand + spikes for 2nd. Spikes + fel for 3rd.
I think you need a cheat death trinket and stack crit for DPS.
So newb follow up question. Kruul’s first annihilate is taking me to like 7% hp when I don’t use anything. Do you guys use soul cleave in that scenario? I notice I’m terrible with using Soul Cleave and usually only use Spirit Bomb. Also during kruul phase, the adds seem to always to Velen instead of me - is that normal?
And for the portal demons - you’re able to Sigil of flame into spirit bomb to kill? I think my damage may be gimped some how. I’m saving Fel dev + sigil of silence for first wave, a holy Ward + trinket for second, and alternate. Gets kind of screwy when I cant do it with Kruul
