path of exile inherite a few system from poe 1

one the ailment super spam system also works in poe 2 from ruffly level 10 or when ever one has the setup ready.

it inherits as well the negativ debuff on passiv tree in case you have activ on account for poe 2 character of both chaos and light paths. the way to fix it is delete all characters and choose one side that removes the debuff if do it with the correct ascendency mixing adds debuffs. this is inherited from poe 1

ascending via the wrong ascention way also give debuff to asenction perks also link to top mentioned and is part of poe 1.

so in simple way trial of sekima need be done for light based classes or you get debuff
ultimatum ascention is for chaos setup like witches. do the wrong one and the ascendency gets debuff
same reason conflict of intresset by mixing light and chaos.

by not mixing in a account and sticking to either chaos or light one can avoid the debuffs
also what ascendency debuff effect what is inherited form poe 1 is how well one preforms the ascendency that also impacts the ascention perks if they have debuffs or not same reason inherited from poe 1.

also light allways is slow at the start of a character both in poe 1 and poe 2. by this its grind lock heavily and takes long time to make it work well

where chaos works and scales well and is easier to get working early

since chaos is the way for power after path of exile lore.

all this inherite form poe 1 and its lore
so choosing light one accept grind heavily slow crawl progression mess

where as choosing chaos easily scaling less grind heavy power increase.

mixing and you get debuff on both

so choose well.
