All the short guides I read never explained it. They’d always say, “get lots of endurance, you need it!”. I kept tying endurance to running and how much weighty armor I could wear. My issue early would be, run into some mobs, try to strike, then I’m hitting the button incessantly wondering why I’m not swinging. Or, something hits my shield and I try to hit back, and nothing happens. For someone who’s never played a game that functions this way, it was confusing and frustrating.
And since I was always short on endurance I didn’t see until much later why you want to strike/strike/strike. I was doing strike, block for a bit. Strike, block for a bit. Didn’t see that each strike in a combo vastly increases the damage done. Finally saw this when I was whacking those giant fire beetles.
