Echo of Duriel Boss Fight Guide

This is one of the hardest boss fights in Diablo 4, so make sure to gear up before fighting. Echo of Duriel can inflict poison, so have elixirs for poison resistance and at least 70% poison resistance. This boss has so many deadly abilities, such as Claw Slash, Poison Pool, Charge, Devouring, Burrowing, and Maggots.
The fight starts with three holes in the ground from where Pang of Duriel’s minions spawn. These minions are low on health but actively spit poison, so deal with them quickly. Beware of attacks like Claw Clash after clearing the minions, and avoid the pools of poison. Keep hitting the boss, and after the boss’ health reaches 50%, the 2nd phase starts.
Again, the second phase brings two Pang of Duriel into the fight. Players should focus on dealing with minions because the situation can snowball in no time.
