Fire/Lightning Trap seems to deal no damage to blight encounters

Hi bug report section,

I dedicated myself again to play a Fire/Lightning Trap this league. But when it comes to Blight encounters or even blighted maps it gets very frustrating.

I did an Uber Atziri deathless "skipping" her phases. The damage overall is not that bad. But blight monsters and bosses seems to take no damage at all.

When bosses break through towers they come to the spore damaged by half of their life and when I try to throw traps at them, they seem to take no damage at all.

Might this be a bug or do I miss something?

I understand that blighted monsters have a rough defense, so do legion monsters aswell, but they aren't a problem at all.

Infos about the build:
Fire Trap average hit is 44k buffed
Lightning Trap average hit is 40k~ buffed
Elemental Pen: 47% + 10% on crit

Notes:
When I find an encounter again, I will make a debug report and upload the screenshot
