kill stuff too fast, can use a bow, but u need OP potions for brutality and crit. then remove hunter and rally(nice heal) and put enless hail and poison injection
general PvE, im planning to do both Dungs and solo open world.
The main advantage if a Bosmer NB is you two dmage bonuses from sneak.
So Vamp Bosmer NB is naturally a sneaky-sneak gank build.
The reason I would go magica would be to unlock the self-heal on the siphon AOE skill - can't remember the name.
Another reason to go magica even with a Bosmer NB is to use Shalk's set and build ultimate even faster - you'll be able to spam Death stroke or whatever morph you take of it.
Also the Bosmer vamp NB should do the Dark Brotherhood dailies super fast. Same with TG dailies. Bosmer Vamp NB is probably the best natural combo for these dailies.
But Bosmer NB's are pretty squishy. Pretty much in the bottom for Dungeons and any solo content with more than 3 opponents.
