Attack chains is hard to deal with
Lunia gold should play as the Azure Knight is almost completely stunned, you can dish out a few combo attacks with a little breathing room at that time. When the stun is about to wear off, just use Ice Arrow and immediately return to kiting. Ice Arrow, Vulnerable Shot, Crow Wings, Wonder Firing and Dead spin are all you need to beat an Azure Knight. The constant barrage of knock backs and attack chains is hard to deal with when the hunter armor is so low. So you should run and use Wonder Firing and Crow Wings during the first 25 seconds of the fight.
