you can stop burning embers by bursting the lock forcing him to heal himself with them = no chaos bolts and as for unending resolve try maby fearing or stunning him during that time so he cant cast? maby jump back and recharge ? plenty of ways to counter that as well or heres another awesome idea as a warrior let him cast it while its on its way time your spell reflect so it gets the chaos bolt and dont be stupid by popping it to early or they can just felflame your reflect. Stop complaining you can easily stop a chaos bolt a 300k hs you cannot stop
