So I want to start a new archer character, but using conjuration for bound bow, summons and raising undead. This being my base perks - http://skyrimcalculator.com/#111063 - maybe changed slightly. Wearing robes so alteration for flesh spells. I might scrap summons and just raise undead.

Not sure what else to go for though, could go for illusion and necrovamp, could go for sneak using daggers as well etc. Anyone had a similar build? Any ideas?

Take the Daggers, you'll be happy when you can take out enemies as they aggro your summons + illusion spells to conceal you.
