I'm gonna make an assassin. Daggers (not dual weilding, because the character grunts every swing and its freakin irritating).
I was wondering if taking destruction (and perhaps a bit of conjuration) would be unworkable. I'd have to split my points between Magicka and Health (otherwise I'd spend the heavy majority of the points in Health). Is this a bad idea?

I want to do dagger + magic support, rather than dagger + archery, because I think it'd be fun. I'm aware spells don't scale at high levels but I assume a mod will be out when I get there.

Dagger + archery is still an option, which means gutting magic and getting more health. But is splitting points between magicka and health really that big a deal?
