Reading this question, is there any difference between magic damage and non-physical damage?
I was wondering if there is a monster that is resistant or immune to non-magical damage, except for the usual bleeding, pervasive, and disruptive damage. For example, this monster could withstand a fire damage coming from a non-magical source, so using a flashlight may not be as effective as flinging a flashlight fire bolt it.
Is there an example of such a creature?
Any resistance or immunity resistance will suffice. If there is a precedent or tradition from a previous edition that a creature has such resistance / immunity, I would also welcome that information.
