When a player champion (a player holding a Title belt) challenges and wins a higher tiered championship belt, the lower Title becomes vacated and is automatically up for grabs at the next Event (regardless of what the Event card says). Any eligible player can challenge for the Title(s). If no players challenge, draw the appropriate number of Superstars to compete for the Title. If only one player challenges, draw a Superstar as the opponent.
This can result in a PvP title match where no player is the champion. In this scenario, roll the die to determine who goes first.
The order of Title precedence from lowest to highest is TV Championship, Tag Team Championship, National Championship, and World Championship.
