you really have to manage your stamina with this one, as you don’t want to get surrounded and die super fast…
I would suggest trying to kite them, just continually move either straight back or move back and circle one way or the other (this is preferred). Doing this the AI will follow you and when you start moving left or right while moving back they will end up falling in line with each other, leaving the chances of getting hit my more than one person very slim.
Also, think about equipping a shield; if an enemy has a bow they will most likely stay back and rain fire on you, and arrows hurt a lot. Plus a shield can catch hits even if you’re not actively blocking, or so it seems.
I would also suggest that when you get the melee fighters a good ways away from the archers, if there are any, to break focus on the enemies that are close to you and chase down and kill the, usually, light armored archers before they can do damage. Killing people makes you bloody, being bloody will intimidate opponents, especially like bandits and villagers and people who “arent real warriors” or whatever; pulling off combos and master strokes causes some intimidation with your enemy as well I’m pretty sure.
The best advice though is to understand that, until late game when your stats and perks are ridiculous, taking on 3+ armored enemies, even lightly armored, is not very realistic and thus not an easy task…KNOW WHEN TO RETREAT. If you are losing the fight, though you want to do it before you’re really injured and your screen is all red and hard to see, just break focus and run; the more health/stamina you have when you retreat the more likely you are to escape; it seems even an AI with full heavy chain and plate will keep up with you so just run in a straight line and take off.
