Despair Herald MTX - Herald of Ash effect is inconsistent

Hi there,

The Herald of Ash variant of the Despair Herald MTX doesn't appear to be working properly. From my perspective, the MTX has three main effects that are noticeable:

1) Explosion
2) Firework trails
3) Broken boulders

The firework trails and broken boulders don't always render with the explosions, and it seems like it's almost instance-based or spellcast-based. Turning Herald of Ash off and on again sometimes solves it, but it's not consistent.

I have no idea how to reproduce this as I'm not noticing any correlation with AoE or other stats. I have tried multiple rendering engines and settings, but nothing seems to fix the issue permanently. A friend of mine also tested this independently and came to the same conclusions.

Has anyone found a way to solve this, and has GGG acknowledged this issue
anywhere as a known problem? This is easily my favorite visual effect in the game when it's working properly, it's such a shame that it appears to have this problem.

Thanks,
