while (!host.dead) {
    chargedHeavy.execute();
}

The forward lunge through Shadow Step and its follow-up that you get from the Bloodhound’s Curved Greatsword in Elden Ring instantly sprung to mind. That thing is a Katana wielder cheeser if you’re patient and lunge right as their attack would land, Whiff Central!
