Foster grabbed one of the new arrows he bought; they were a little different to the ones that he used until now. A few of them broke today while fighting against the monsters, so he had to get new ones anyway, but these seemed to be a little heavier than the arrows he usually used. Which in Foster's mind quickly made sense; a heavier bow being used with heavier arrows didn't seem unreasonable. And obviously, heavier arrows would also lead to more damage too.
He placed his guard onto his arm so that he wouldn't end up destroying his forearm while practicing and quickly nocked the arrow on the bow. He stepped in front of the target and held his bow forward. Now, obviously there weren't a lot of ways to deviate from the 'generic' archery stances. They were pretty optimised, and most techniques that played with this were the kind that allowed for optimised shooting in different situations.
