If you’re having trouble against muskets just switch to heavy armour

It takes them 4 shots to kill you instead of 2.

Yep, recently discovered that exact scenario after swapping to heavy SnS to try out. Sure you can block the ranged musket till your stamina is exhausted and they will kill you quickly because no way you can get in range in time to fight muskets.

Or the musket user is at medium range and they shoot your stamina down for shield, then throw a sticky bomb, it’s explode and they kill you with next 2 shots.
