How to Beat "Emma, the Gentle Blade" Boss Battle - Sekiro
Combat Tip 1: When closing in, strafe Around Emma.
By strafing around her, you will be able to avoid most of her attacks.
Aim to strike after her attacks with your own to damage her health & finish her off.
Combat Tip 2: You can Parry as well.
Another idea is to lure Emma into a trap and make her counter your attack so you can parry her returning strike.
This may take some practice to learn the parry timing and this is a faster alternative to the strafe tactic.
