Need Help W/ Wrath Of The Mummy

I'm a level 38 archer, and the boss fight in the wrath of the mummy quest is really difficult! I would appreciate some help with it. I am looking for either a warrior or assassin around my level or a little bit higher to help out. Message me if you're able!

 

it's in fact pretty hard bring hp pots and grind for better armour
use wynndata to show me your current build so i might have an idea

 

I'll post the link to my build as soon as I can

 

hide behind the columns, strafe out, and arrow bomb
rinse and repeat
dont let him hit you, he has ls

 

Your advice really helped, I beat the boss. Thanks!
