Swordmaster gets duelist perk (extra armor ignore).
Hedge knights sometimes come with famed weapons that have damage ups.
Double grip also adds 25% so watch out when breaking leader’s shields.
Orc Berserkers sometimes come with mushrooms that add 50%? dmg when consumed.
I believe Hedge Knights also have Killing Frenzy and Berserk but i’m not 100% on that.
I don’t think it’s possible to deal that much damage with a boar spear. Maybe 2 hits if he doesn’t wear a shield. That mount of damage is about as much as a polearm hit like a Long Axe or Billhook even Pikes and Hooked Blades shouldn’t do that much damage.
