The arrow itself seems to function as pure IPS. Let's say you mod Heat + Electric (this is Radiation btw). The arrow itself will be able to proc Impact/Puncture/Slash or Radiation. The cloud has its guaranteed Toxin proc and will additionally be able to proc Radiation or Toxin.

It's even more interesting with three elements, as your arrows and cloud will be proccing different elements. Suppose you have Heat + Electric and Cold. Your arrows will proc IPS, Radiation, and Cold. The cloud will proc Toxin, Radiation, and Viral (Cold + Toxin).

This allows you to (eventually) proc combinations of two combined elements plus one normal element, something most weapons cannot do.
