If you try to lower the resist of the leech with threnody (-50 water resist) and then try to nuke water, you still get auto 1/2 resist. I'm not sure if you can stack enough resist to possibly get a different result, but it's looking like those strong elements are just 1/2 resist and you can't do anything about it.
Since it seems like this is a permanent thing possibly I might try to compile a full list.
Also, it seems like certain NMs have additional resists factored in, either by trait or some other mechanism.
