Utilize Ashe's potent CC (constant slows, global stun ultimate) and Hawkshot (E) vision to control the map and provide immense utility for your team.
With Lethal Tempo and her Q skill's attack speed and damage amplification, Ashe boasts high sustained damage from early on, scaling powerfully with items.
Lacking an escape ability, Ashe is vulnerable when caught; prioritize careful positioning to survive and consistently output damage.
