I know on hit has been done, but I'm trying to narrow the % of hp his ult will do applying on hit effects from 
combined with 
. I'm just not sure how to calculate it. Hydra ik will do 5% hp during the five hits of the ult, however states current hp, and I want to figure out the total hp% from max 100% health. So how do convert the 8% current hp to combine it with hydra for a total?
khorney1 votesyou want rage blade my man
TheFallenShaw1 votesno just wanna do the math actually, not making a build. used ww as and example bc of when he was broken back when we had devour in the game.... I miss stacking items
Altonius Amakiir1 votesit will deal 5% of your max health+ 34% of their max health with just those two items passives(+the actual ult damage and passive on hit damage).
edit: In actuality the damage from BoRK would be smaller because the damage from WW passive, regular ult damage, and titanic hydra would do damage too and I based that number on solely its damage from 5 passives. But it should be close enough.
Altonius Amakiir1 votesThe real number would follow this for Warwick's ult with only those two items: (M=your max health, m=their max health, L=your lvl, R=ult ranks, [X#]=new health after # of autos, A=armor multiplier, G=magic resist multiplier) m-(((.01M)+(.08m))A+(10+20R+.4(122.43+(L-1)3.375))G)=[X1] [X1]--(((.01M)+(.08[X1]))A+(10+20R+.4(122.43+(L-1)3.375))G)=[X2] [X2]--(((.01M)+(.08[X2]))A+(10+20R+.4(122.43+(L-1)3.375))G)=[X3] [X3]--(((.01M)+(.08[X3]))A+(10+20R+.4(122.43+(L-1)3.375))G)=[X4] [X4]--(((.01M)+(.08[X4]))A+(10+20R+.4(122.43+(L-1)3.375))G)=[X5]
Based on when I usually have second item bought by, and the items given, the numbers would be: L=13, R=2, M=2219 and I will use m=1412(Jinx at 13 as well as her magic resist and armor at that level) and m=3000(average tank health full build as well as 65% armor and magic resist). This is to show the best case and worst case scenarios for damage(I will show in flat and % for you).
Important part: For the Jinx scenario: [X1]=1240 [X2]=1076 [X3]=920 [X4]=772 [X5]=631 a total of 609 damage, or 49.1% of her max health. For the tank scenario: [X1]=2868 [X2]=2740 [X3]=2615 [X4]=2494 [X5]=2376 a total of 624 damage, or 20.8% of their max health.
These numbers are so different from the original I posted because in this I took kit damage into account, and enemy resistances.
