If you want to send as many hits towards your enemy as possible, you'll want to avoid using your sword's finisher but there are still choices to make. I find the two most useful techniques when using three hit swords to be these:
- First attack > second attack > shield cancel > first attack > shield cancel > switch > switch back > repeat
- First attack > shield cancel > first attack > shield cancel > first attack > shield cancel > switch > switch back > repeat
So which one wins? I find both to have pros. The former feels faster at least with toothpicks but on the other hand, said weapons have greater range on the first hit.
The first option is probably easier to do as well, as there's a bit less input and most notably, less shield cancelling.
Charge Attack>Shield>Repeat
