Box Collision Object
From Runic Games Wiki
This Particle Object creates an invisible cube that particles will collide with. This is of limited use, since collisions can be expensive if there are a lot of particles, and there aren't many situations where colliding with an invisible cube looks cool anyway.
There's probably a better way to get the effect you want.
