A Razmiran cultist: the epitome of a practitioner of false divine magic
Through deception and the careful use of arcane magic, a mundane entity can appear to grant divine magical abilities to its followers. This practice is referred to as false divine magic.
A user of false divine magic might be able to deceive witnesses of their spellcasting into thinking their use of a hidden arcane magic item was a divine power. Others might use a false divine focus to fuel the material component of an arcane spell.
The most contentious source of divine magic is Razmir, known to his followers as the Living God. The masked ruler of Razmiran spreads his false faith through lies, arcane magic, and magic items that make his followers' abilities appear to be divine miracles.
