Why so little strength????
[Yareli]'s Ult does more damage based on how many enemies are in her Riptide so when you use it normally you don't get alot of damage out of it regardless of your power strength, but with Larva on the build you can collect all the enemies in one spot immediately then cast Riptide in the same spot killing all of them.
I wanna overkill the enemies even more!
If you are feeling confident about ur survivability you can replace [Redirection] with [Umbral Intensify].
Have fun!!
EDIT: Build could still work with [Mag] Pull in place of Larva
