Magic Item Quick Reference for Dom 3?

[Huntsman]

I've started doing the update and I'm wondering what the special property "On Targets" means in the Dom3 manual. For instance, Smasher has the special prop "On Targets: Crusherknack".

Initially I thought it was the same as "On hit", which is self-explanatory, but there are references to "On hit" as well.

Anybody have any idea? I'm assuming it means that actually "hitting" your target isn't necessary for the effect to fire. Maybe you must actually target an area or unit, perhaps...
