Fighter/11th/Sharpshooter

Volley

At 11th level, you learn to unleash an unstoppable flurry of projectiles. After you use your Attack action to make two ranged weapon attacks, you use your bonus action to make a volley.

You can make any number of ranged weapon attacks as part of a volley by expending 2 stamina points for each one. You can't move between volley attacks, and must decide on all attacks and targets before you make any attack roll for the volley. If you make multiple volley attacks against the same target, you only add your ability modifier to the first damage roll, not any subsequent rolls.

You can't use techniques as part of a volley.
