Bombarding clones interactions faster proj

The Gravy Train (Gravicius in Transport) gave me a Voltoxic Rift with supported by lvl 10 faster proj corruption.

It seems bombarding clones is the goto build for this bow. Before I waste a ton of time farming beyond to link this thing. I'd like to know how faster podj affects the clones.

Does it just make me shoot the arrow faster, thus spawning the clone faster, does it makes the clones attack animation faster (they cast RoA) maybe both? Or so.ething else entirely??
