Darkness - acolyte of Chayula - Damage taken from ES before darkness

Multiple type of damage are being taken from the ES while darkness is still full and isnt going down at all.

I cannot find any specific information if that is an intended behavior or not.
Nothing is specify on the ascendancy node or online when i do research.
So if this isnt a bug maybe it should be clarify.

The ones that i noted (but there are probably others):

Vall embalmed banner
River hag whirlwind
Undertaker attack
Purple cloud from plants in chimeral wetland and from Ill-fated explorer
Filthy crone ground circle attack
Foul sage red Bubble
Temple of kopec sun effect
Ketzuli high priest beam (ignite?)

Poison cloud, blood pool, abyss ground effect and generaly every ground effect.
Being ignited.
