Mark of Caesar

The Mark of Caesar is a miscellaneous item in Fallout: New Vegas.

Characteristics
Given to the player by Vulpes Inculta upon exiting The Tops Casino after completing Ring-a-Ding-Ding as part of the quest Render Unto Caesar, the Mark of Caesar allows safe passage to Caesar's camp even if the player has a low reputation with Caesar's Legion. If the player killed Vulpes Inculta before doing the quest The House Always Wins, a messanger will contact the PC after they exit the Lucky 38 after the PC has accepted The House Always Wins Part II. Without the mark the player cannot complete The House Always Wins.

Bugs

 * Caesar's Legion may still be hostile towards the player, even when carrying the Mark of Caesar. This occurs when the PC travels with a companion that is hostile towards the Legion (I.E. Craig Boone).


 * They will also be hostile if you are wearing another faction's clothing while wearing the Mark of caesar (I.E. NCR).


 * Attacking Legionaries, or otherwise gaining Caesar infamy, will result in the failure of the quest Render Unto Caesar despite holding the mark.
