Splash
Your hit spills onto every other foe on the field. The one you struck takes the full weight of the chain, and the rest take a share off the side, which is how a crowded fight comes apart.
In detail
Charms and hero passives each contribute a splash percentage for their element, and they stack linearly. Splash always lands at its base value: weakness and resistance never apply to it.
