Illusory object has the following spell description:
You create an illusory visual image of a stationary object. The entire image must fit within the spell's area. The object appears to animate naturally, but it doesn't make sounds or generate smells. For example, water would appear to pour down an illusory waterfall, but it would be silent.
Any creature that touches the image or uses the Seek action to examine it can attempt to disbelieve your illusion.
Makes sense. Incorporeal visual illusions are a staple of D&D 5e and I think I have a firm grasp on the difference between disbelieving and knowing-it-is-an-illusion. No problem. However, the heightened version of the spell:
Heightened (2nd) Your image makes appropriate sounds, generates normal smells, and feels right to the touch. The spell gains the auditory trait. The duration increases to 1 hour.
FEELS RIGHT TO THE TOUCH?
How do I - how does an - what? It's an illusion. It's incorporeal. Touch is a VERY Corpreal sense. Baroreceptors man... touch is a sense that requires force. How the heck does an illusion "Feel right"? A brick wall only feels right if it supports my weight, but I don't expect an illusion to be able to do that. A hot coal only "feels right" if it burns me.
Does anyone have any idea how this actually manifests in gameplay or how we are supposed to interpret this? Does this somehow make the illusion semi-corporeal? Can I suddenly place a dagger on top of my illusory table? How does one touch an illusion at all?
Was thinking about this all last night, I'm flummoxed. Any help would be appreciated.
