How can I get this spider to stick to an animated mesh as it deforms?

So if casting a ray down isn’t already what the spider uses, how exactly does it get it to stick at all currently? Getting one object to stick to another as it deforms is something I’ve been trying to do in animation for months, does it only work in BGE? An object isn’t necessarily moving at all, just deforming from an armature.
I see no boolean option for properties, do I apply the property to the spider or the object I want it to stick to?

Here is my take on: walking on animated objects
