Hmm sorry to be a pain but it still doesn't work for me. I have tried a bunch of things and for some reason no luck yet on my end. I don't use the exparam fix plugin. I am not sure that you tried the right field though, it wouldn't be the Block Chance or Block Amount field but the Block % field which is above those. It normally looks like: Block Chance Text Block %
Where the fields you have shown it working all have Yep status menu core in the name the Block Chance Text area does not. I am thinking this might have something to do with yanfly not recognizing it. I am looking at the first tab in the status menu that's labled general by default, not the attributes tab. It also appears wrong in the equip window.
