Before they're given their first Long Bow, aspiring archers on Oriath are taught the art of the Arrow Rain. When the student is ready to be tested, he is taken out to the marshes, and commanded to fire a salvo at a flock of geese. The aspirant must bring down at least a dozen birds with one barrage, or it's back for another year of training and discipline.

Naturally, the Rain of Arrows technique is often used to devastating effect on the field of battle. A skilled archer fires a single enchanted missile aloft, and when it descends, it multiplies to carpet an entire area in a lethal shower. Be wary if you ever behold an enemy archer pointing their bow skyward.

Description on the official Path of Exile website

Rain of Arrows is a ranged attack skill that fires a number of arrows in the air, dealing area of effect damage after a short delay.
