[RPG] Any way to overcome a Paladin’s immunity to disease without GM fiat

diseaseimmunitiespaladinpathfinder-1e

Is there any way to overcome a paladin's immunity to disease without a gm fiat?

The goal is to make a paladin able to fall ill through any means possible without him losing his immunity, but instead somehow piercing it, be it with magic or through an item.

Best Answer

A poison that appears to be an illness.

Alternately, a Curse, like Mummy Rot. (Apparently this no longer works, since 3rd edition D&D started.)

Divine Health (Ex)

At 3rd level, a paladin is immune to all diseases, including supernatural and magical diseases, including mummy rot.

Functionally, to give a Paladin a normal any disease you will require GM fiat. Note that I am including researching a new magical gizmo under GM fiat.
