How do I turn part of an sprite invisible

Okay so i have an somewhat of an confusing thing here.

I am trying to make an object turn invisible but only in the area the mask is overlapping.

Sort of an fog of war but limited to only one object that acts as the fog but the "fog" also have an texture

Hope someone might have tried this before and can help me out

Until then i will continue trying it out

Thank you!

I am not 100% sure, but I think blending might help you:
