I recently returned to the game and I decided to make a Bosmer NB, with the intent to become a vampire in order to capitalize on the bonus stealth damage. My goal is to make a DW build. I have read some guides and I am confused because some recommend 7 light for spell power while others use 5 medium/2 light for extra crit. I've been changing back and forth between light armor and staves to medium armor bow/dw with more stamina abilities. Any advice?
