hi i got a question

is % elemental damage as extra chaos dmg calculated in POB already itself or do i need to activate it somewhere?

im looking to buy an expensive wand for KB wander but it says its only 5-8% more dmg with an 20+ ex wand?

so im not sure if more flat lightning is just as good as %extra elemental dmg as chaos?

so i just wanna know if % elemental as chaos is already calculated in the pob dmg shown or not

thx alot!
