Just wanted to ask about Ignite prolif, as I was looking into some builds, most of em have good clear, ofc thanks to prolif, but some builds dont use support and just rely of herald of ash?

I read the skill and it says that it transfers only Overkill damage, does is scale with my DoT damage somehow or do they get prolif somewhere else and Im just hella blind?
