how a crit chance support gem interacts with DOT?

[cheerfullygrimm]

so i am making a dot witch build and the t2 support gem 'potential' allows the skill to use power charges for increase crit chance.
my understanding of the mechanics of dot is that each tick of damage has its own crit chance. this leads to the two questions i have.
if i apply this to essence drain(which is my main dps), does the crit chance only apply to the hit damage or does it also affect the dot as well? if the ladder, will the crit chance boost spread as well when contagion also spreads it?
i want to say yes to both, but i am having trouble telling a difference in my non-scientific test.

dot dmg can't crit, u boost essence drain dmg by applying withered to enemies.

no it can crit. the detail arrow on the skill gem and dot tab shows crit chance. plus, i remember something about pointing out each instants of dot has its own crit chance so people don't spam until they get a crit and every dot after is a crit.

you don't remember anything because you're also wrong about that
people are tryiong to crit to get a higher DOT. since magnitude of a DOT is based on the intial hit as magnitude modifiers. DOT's do not crit unless otherwise stated

dot can't crit , like essence drain .

what you describing is ailments , like poision or burn, these can be applied with crit to have higher damage, so if you run poision build you scale crit and crit dmg so poision applied with crit hits applies more dmg.

Ailments and dot spells are 2 different things in this game. There's plent of yt videos explaining stuff, watch all details there !
