Reloading Strike

ACTION
Activity 1 action

Requirements You're wielding a firearm or crossbow in one hand, and your other hand either wields a one-handed melee weapon or is empty.

You make a melee attack and reload in one fluid movement. Strike an opponent within reach with your one-handed melee weapon (or, if your other hand is empty, with an unarmed attack), and then Interact to reload. You don't need a free hand to reload in this way and this reload does not trigger reactions.
