Went through Korvaak with a Vitality/Bleed Spellbreaker.
The fights with Kymon and Korvaak were pretty easy, but the character is not deathless, dying 4 times near the end of the leveling process, once at level 90 to a wraith hero that dropped an aether crystal barrage from the sky, once at 91 to the tablesaw projectiles of death from Ekket’Zul going through the rift on the way to Malmouth, and twice at level 94 to Loxmere Nightmage.
I finally assembled the full Blood Knight set and put it on at level 96, due to bad luck transmuting and the character being perpetually poor because all my iron bits were going towards yet another try at getting the shoulders. Since I was trying to wait to upgrade gear until I got the full set and I had relatively little to spend on augments, I had low armor and not much overcap on resists, which explains the deaths.
The maximum damage ever taken by the character was 8902, which is a lot for a character with only 10k hp. However, that close call was one I’d survived that occurred before any of the deaths.
Korvaak’s death:
The projectiles from the bloodbathed are rather pretty:
Damage breakdown for Blade Burst with Lethal Assault and Bloodthirster up:
Normal playstyle is to use Bloodthirster offensively and kite a lot. This gives you extra bleed damage that is up most of the time, since each lasts 8 seconds and you have 2 of them, and if you’re fighting bleed resistant enemies, you can turn it on after getting a Rend proc.
The amount of bleeding damage on Blade Burst itself is relatively small compared to vitality decay, however there are other bleed sources in Rend, Soul of Nazaran, the Bloodbathed, and Bloodrite gloves. Overall it is definitely more vitality than bleed focused, although it would be possible to focus in the other direction by putting Rend on Blade Burst, spending points on cunning instead of spirit, using bleed rings instead of vitality rings, and rearranging the devotions.
I did not use the skeletons from Raise the Dead or the shadows from Unknown Soldier on this build, however, that would be an option for a more bleed-focused version of it, and it would be quite amusing to have so many pseudo-pets running around.
This build worked fine, but would work better as a Reaper or Trickster, with Witch Hunter and Blademaster also possibly better, and it would work as any Nightblade class. It could fill the bleed slot for Saboteur, but something with phantasmal blades or blade trap would likely work better for that.
