"Inevitable Agony" + "Hayoxi's Fulmination" = NO curse effect.

So yeah, the Chronomancer ascendancy skill "Inevitable Agony" does literally nothing when supported with the lineage support gem "Hayoxi's Fulmination".

Very easy to replicate; Without the support enemies take a chunk of damage when the curse ends (assuming you hit them during the curse duration), with the support gem the curse itself does nothing.

What a let down.
