The grind for gear is already kind of silly, we're not going to trivialize anything by having our scant orbs we already have to farm for drain potential we have to budget when it does literally, actual nothing to the item.
Orb of Digging is a particularly silly example of this. It doesn't need to just fail outright. There's no fun in that. Sure, corruption affixes are potent, so those orbs can keep their risk, but even those are a bit harsh given you're not using them on things you put energy into. Destroying the item? That's extreme for no good reason, even PoE doesn't do that to you unless it's some special version of corrupting an item like at the temple.
Please consider.
