Just something about Twitch's ult+runaans interaction....
So twitch ulti increases twitch's range and lets bolts pierce enemies.
These bolts deal 100% to the 1st enemy, 80% to the second one, third takes 60%, 4th takes 40%, with a minimum of 40%.
Runaan's deals 40% AD to enemies within range that are nearby, and they can crit.
Therefore- assuming that 3 people are lined up
1st person will take 100% of Twitch ult's damage, and 0% damage from Runaans.
the second person will take 80% of twitch's damage, HOWEVER, Runaan's deals 40% damage, in total for 120% damage. 3rd person takes 60% from ult ,40% from runaans for 100% total.
The first and third person will take 100% of twitch ult's damage, yet the person right behind the first one will actually take 120% damage.
