I’m playing season 3 online, Primalist Shaman.
When you use Jormun’s Wrath vs a group of monsters, the audio cumulate. So after I’ve done it a handful of times (depending on how many monsters I hit), the audio starts to stutter and sounds like it have too many layers of the “frost hitting monster” sound. If I keep going, the whole game starts to stutter as well.
I*ve also given Storm totem ‘blizzard’ which also add to the frostbite stacks.
It started getting bad after lvl 20+
