The priest plays in the innocent team and his role is hidden like most other roles too. He has one very powerful tool: the holy deagle. With the use of said tool, he can create a powerful brotherhood of innocent players. Players inside the brotherhood see each other in the scoreboard. But he has to be careful, there are a few things to keep in mind:

• most innocent players are added to the brotherhood, except detectives and sniffers since it is too easy to confirm them
• shooting a detective or sniffer with the holy deagle deals 30 damage to them
• shooting an infected host or necromancer kills the infected host or necromancer, the same goes for sidekicks
• shooting other evil roles kills the priest while still damaging them like detectives
• shooting a marker will mark the whole brotherhood
• if the priest is converted to an infected, zombie (necromancer) or sidekick, all other members of the brotherhood are converted too
• while only innocent players can join the brotherhood, players stay in the brotherhood even if they are converted (e.g. jackal, unknown, ...)

Additionally the holy deagle has a cooldown after being used. The cooldown is short by default if you missed the target but a higher cooldown is used if you added a player to the brotherhood.

Besides the normal role convars found in ULX, there are these special convars:
