Ashe (the Frost Archer) | Champions recommended for a start League of Legends Guide

Ashe serves as a long ranged ADC. In early game she is a bit weaker than other ADC, but controlling her is easier. Later in game, she reveals her true potential. One of Ashe's abilities is Frost Shot (Q), which can temporarily slow down an enemy. Another very useful ability is Volley (W) - it enables Ashe to attack several targets at once. Note that arrows stop at the first opponent on their way, so they will not hit a champion standing directly behind a minion. Hawkshot (E) can be used for scouting. Sending the arrow in a given direction will illuminate the area, revealing any possible danger. Finally, Ashe has Enchanted Crystal Arrow (R), which is best for initiating a team fight. Well-aimed arrow can stun up to several opponents, giving an upper hand to your team. Note that the time of stun depends on the distance the arrow has covered. The farther the target, the longer the stun is. The arrow can actually fly across the entire map. Gold is best spent on items which add bonuses to physical damage, attack speed, critical chances, and life steal.

Strategy:

When Ashe is out of combat she gains focus stacks, which, in turn, increase the chance of critical hits. Remember that you should attack your enemy first to use that advantage. After the first attack it is best to focus on farming and harassing enemies by W->AA.
