- Given a Cleric 1 / Wizard 4 / Ur-Priest 2 (character level 7). This character has both arcane and divine spellcasting and is assumed to meet the requirements for Mystic Theurge.
- Takes 8 levels of Mystic Theurge (Cleric 1 / Wizard 4 / Ur-Priest 2 / Mystic Theurge 8), which advances the spellcasting of the Wizard base class to 14 and the Ur-Priest to 10.
- Ur-Priest only has 10 class levels available to progress through. What happens on the next level of Mystic Theurge?
- The character is still only an Ur-Priest 2. What happens if the character takes a level of Ur-Priest, to advance to Ur-Priest 3, but the spellcasting level of the Ur-Priest is already Ur-Priest 10?
