Until ZOS in their infinite wisdom decides to nerf Cloak as well, of course.

Having played it since launch: I'd say that it's more difficult now, but not necessarily less effective. You don't do as much burst on account of nirn (which will be balanced soon), so you have to plan things out with the long con in mind -- but that's the nature of 1vX anyway.

Two main pieces of advice, I think. Plan your skills out in terms of how they'll work together, rather than what they'll do by themselves. Concealed weapon and cloak on the same bar, for example; you might want to figure out a good skill to pair with siphoning attacks, too, for resource gain.

Finally, don't be afraid to play around with different armor combinations! It's possible you'll find all light to be a little low in the defense department, depending on your playstyle. The magicka Nightblade is something of a jack of all trades-- and in a 1vX situation, it really needs to be-- if all light (or even 5) doesn't give you everything you need, don't get too hung up on the 5pc light passives that you end up unsatisfied with your durability! Try everything out that you can.

I like my magicka Vamp NB with destro staff. And as mentioned above, try to plan your skills on how they work toghether

I'm curently using in my main bar

Siphoning Strikes (for sustain)
CW (for mobility in stealth and close range, and armor increase)
Lotus (gap closer)
Destro Clench (Gap opener)
Reaping Mark (reduce armor and MR and more sustain)

U -> clouding swarm


In stealth: Reaping mark + full heavy attack + lotus + clench + basic attacks (while walking to the enemy) or lotus again + CW and light attacks (to recover magicka and stamina)

You can also use RM + FHA + Lotus + Ultimate + CW (to set him Off Balance)+ basic attacks (Ideally light to recover ultimate)

For my second bar, I'm still working, but I realize that the combo Grim Focus + FHA + Impale can do a lot of dmg. Maybe a combination of those 2 and the first bar...

GF + FHA + lotus + clench + LA (while walknig to him) + CW + Impale

I think a stamina version (2 handed) is possible too
