And Summoners/Scholars can put diseases on these.
There's actually a logical reason behind this. The poison the NIN apply to their daggers are from various poisonous creatures, whose venom melts through all manner of things. The various SMN/SCH DoTs work because they're corrupting aether, something all matter has in Eorzea. But you cannot inject actual poison into something non-living, nor can you Disembowel something non-living. This is why neither of those two abilities work on things such as the boulders in Copperbell HM.
