Need Help With Amadel

I'm a level 75 archer wielding Bob's mythic Bow and all legendary armor. Despite this, I can't get past Amadel's third incarnation. I'd appreciate if anyone would accompany me when I log in tomorrow (in approximately 12 hours) to defeat the boss.

 

What armor exactly?
And I can help

 

I can't exactly remember the names of the armor, since I came back from being inactive, it's the old best armor that ya could have at that time in the game, which I believe was adamanite, stalagmites, and some other lvl 75 leggings.

 

If you have Champion armor still, I'd suggest using that over the old endgame
Using the old endgame set all together isn't that great

 

Yeah, I seem to have come across better armor just going through the new quests around my level. Also...I haven't finished the tower of ascension yet, probably because the last time I was in there a glitch between floors deleted my "bob's mythic dagger."

 

I don't know if you still need help with this quest but I am also stuck on it (however I am on the second boss)
I'm a level 70 archer using the Clairvoyance. Sorry if I'm too late!
