First I'd like to say that this isn't a typical sap tank. This one is supposed to have a bit more damage (and of course the trade off is less resistance) because I prefer actually killing rather than just sitting in a mob of players and just not dying. With that said in all the builds of sap tanks or even magicka nightblades I haven't seen one like this and so most of this build is based on my trial and error or what I believe would work best for it. It uses a destro staff and SnB. I use destro staff because it's easier for me to weave heavy and light attacks to proc assassin's will. Now to the build.
The gear is as follows:
5x Kagrenac's Hope (all light because I don't have all the undaunted passives).
3x Willpower (spell dmg and robust for a bit added stamina for break free and blocking)
1 Kena
2x Torug's (head and destro staff)
and either 2x endurance or 2x death's wind (sword and shield)
Bar 1 Destro
Swallow soul
Impale
Mass Hysteria
Structured Entropy
Merciless Resolve
Soul Harvest
Bar 2 SnB
Swallow Soul
Mirage
Sap Essence
Siphoning Attacks
Refreshing Path
Soul Tether
