lets take monolith with mod : monsters have resist equal to 50% their life.
we can assume that average monster life in monolith is 4000.]
So elemental resist is around 2000.
And without shock monster will resist 2000/(2000+4000) = 0.33 => 33% damage will be resisted.
Now my stats that effect shock:
lightning blast
60% shock chance (lightning blast - volatile lightning)
passives
16% (ceraunamancer) 50% shock effect (‘arcane current’ 1 point)
gear
43% shock chance - tome of elements
142% shock chance, 494% shock effect- stormtide
49% 46% shock effect - invoker static charge
11% - idol
sum:
321% shock chance
589% effect
3.21 stacks * 100 penetrtion (1+5.89) = 2211.69 - penetration per lighting spell hit
So after first hit monster resistance will be:
-211/211+4000 = -0.05,
after second hit monster resistance will be:
-2422/2422+4000 = -0.37,
So 3 hits in a row with damage X will result in damage taken like this : 0.66X , 1.05X, 1.37X
So second hit will do 50% more damage then first, third hit will do more then double damage of first hit.
But in reality seems like all 3 hits do same damage.
Its need to be fixed.
