Magicka Necromancer BG PVP viable - Construye - ESO

Necromancer is missing a lot of viable buffs so i slapped oakensoul on it. Oakensoul comes with lots of disadvantages like missing multiple hots so you need to be careful with your health.
 

Cast Blastbones all the time. Elemental Susceptibility is your spammable. Its important that you weave this one with light attacks.

Spirit will give you 10% damage reduction, the heal is not really that good. You could think of slotting vigor instead. That gives you a better heal but less damage reduction. Not that your stamina pool will be under pressure then because you cast Blastbones, dodge, sprint + vigor.

Flame reach is your stun and you should use it in combination with the blastbones hit or to push enemies into your flesh atronach. Use flame reach from time to time to get some pressure of and during burst phases.

You got a lot of penetration thats why your blastbones will hit with full damage most of the time (tooltip divided by 2 because of battle spirit)

Using potion when you get bursted saved me a lot of times. I also recommend to get some detection potion with restore magicka.
