Full power SPVP necro build :
48% crit, 68% crit damage, 3200 power.
Death shroud 1 hits for 4k on crit and applies vulnerability and might to you. Life transfer hits for 4k in aoe.
Only 2k armor but can go to 2.4k when you channel, and you will channel a lot. Siphon life hits for 2k~3k and make you gain 200 per hit. Axe #2 also deals solid damage but it’s nothing compared to your wells!
Well can crit, and they will crit for ~1.5k on pulse, while adding vulnerability and converting their boon to condition. You root them for 4 sec and then you use your wells!
A kitten ton of CC: daze (2 sec), chill (5sec), root (4sec), cripple (2sec), fear (2sec), vulnerability (can go to 15 stack easily), and golem knockdown.
2 spectral armor : used for the overall lack of defense and to fill that deathshroud bar
Warning: This build is not for beginners, you need to be skilled with your deathshroud.
