Trying to make a Dunmer assassin and I'm not sure what to go for.

I want him to be somewhat stealthy and deadly.

I've heard that Bound Dagger is sorta glitchy... should I go for normal dagger instead?

Assassin? Go for normal dagger. Bound Dagger's pretty much support for dagger-using mages - you'll want something you can temper and custom enchant, though.

Assassins doesn't always rely on magic ya know. normal daggers would deal much more damage anyways if your level in conjuration isn't that good.
