Second, two star draugr archers are also incredibly dangerous if you're trying to parry it with the basic wooden shield. No, this isn't a bug. They really do hit like a truck.

Upgrade or replace your gear and be smarter with your approach to the swamp.

I'm trying to block/parry it with the ironbound shield but it almost one shots me through it as well.
