Solo Hardmode Delve Boss (??) Nullaeus Kill as Blood DK on Day 1

I was 240 ilvl for this kill and I'm like 30th kill or something in NA leaderboards. I did it as blood because unholy was getting smashed after the add phases, probably due to low ilvl. Valeera is level 45 healer with crit amp and a garbage utility one, but I would use the cd reduction utility I think. You need to build blood shield and use 1 or 2 defensives every tank buster, depending on your gear, but I'd imagine every tank needs to solve that somehow. You should be picking up every valeera orb before the hit for healing so the death strikes are mostly for blood shield. I also save offensive cds for the add spawns. After 25% the tank buster does a lot more dmg, so you really need to have defensives ready and stack blood shield and just full send the boss while ignoring the add, if all else fails. If I did it again I probably would zerg boss over killing the add. Hooray, I think this was my 4th pull as blood, but did 2 as unholy before that so 6th total pull. 00:00 Start (100%-75%) 02:24 (75%-50%) and first adds 05:46 (50%-25%) and second adds 09:10 (25%-0%) and third add
