would frost gear work well on her? after all she mainly does aoe.
frost gear doesn't work with aoe attacks. it triggers when the equipped champion is attacked, not when they make one. it works best on tanky champions or champions that place provoke debuffs to maximize the number of attacks recieved. you'll need to use either daze or stun equipment if you want to give dark athel a cc ability.
that aside, zed and krama are both correct. she's not really worth building but if you're going to do so anyway, focus on crit, speed, and attack.
