Bows are mainly for players who love to keep their distance from danger and prefer to attack enemies from afar. You're a range class so you will very vulnerable to attacks if you get too close to melee baddies. As you progress through the bow proficiency levels, the amount of arrows that you can shoot in every attack increases and they will spread out to hit more target. By maxing out the bow proficiency, you will be able to hit lots of enemies in one single shot and cover a huge area.
Besides shooting more arrows, you will be able to unlock charging skill just like the other classes. Charging skills for bows have great area of effect and they can deal massive damage over time. Be sure to aim properly before charging up the skills as you will not be able to re-position yourself while charging. Once the charge is finished, the arrow will damage a huge area in front of you.
