act 1 king of mists phase 2 ramping up dot that does insane damage-- how to get rid of the dot?

in his phase 2 he puts an ending dot on me that intensifies my the second.
this dot is called

shadow surge

its starts at 1 them ramps up +1 every second.

it doenst go away and has no timer-- it end up eating thru my 450 hp in about 10 seconds.


is this a bug? as all the guides im reading do not mention he doesn this, or is there something i need to do to get rid of it?

youre literally the only person ive seen mention it. i watched several videos and streams of people fighting this boss and not one of them gets this icon on their screen. i play HC and i continued in standard to see what it was it was the only way i could find out what it was called. i got the icon i backed up to see if it would tick down and nope. so im just gonna do it again in hc and esc scum is i see it pop up haha.

isn't it from the effigy thing he pops down now n then?

I got killed by some insane dot one on an early playthrough but never seen it again after that but i started killing that effigy thing after that but if its not that then i have no idea.

Kill the totems he puts down. If you want, leave one up and watch the pulse come from it.
