After Patch 10.1.5 launched, players have noticed that Mythic Zskarn is not casting Unstable Embers — significantly decreasing the difficulty of the encounter.
One of the main mechanics on Mythic Zskarn is Unstable Embers which deals high damage to 4 players but when the debuff expires, it fires a line towards them Elimination Protocol. Without Unstable Embers, there is also no Elimination Protocol which significantly reduces the throughput required to defeat the encounter.
