Weird "Mage Masher" message after using modded skills

[psiiijay]

So every time I use a skill I made I get a "mage masher" message after I hit.. I searched the text for battle msg or something but didn't find anything like that.. Anyone knows what's the deal?
I thought it might have to do with silence but I turned off everything - I have a normal death spell, or a normal charm spell with a changed formula and VFX but I still get it every time...

No one knows what I'm talking about?? It's driving me crazy!
