Caesar's Favor

 is a repeatable quest in Fallout: New Vegas.

Quick Walkthrough

 * (First time only) Receive notification from Disguised Frumentarius
 * Travel to cache location near Cottonwood Cove
 * Open any of the metal boxes.

Walkthrough
A Disguised Frumentarius will come to the Courier and tell them that they have been faithful to Caesar, and are now allowed to make use of a Legion supply cache which is periodically replenished by Legion members. He then departs.

The player is given a quest marker which leads to the cache, located on a rock ledge south of the Sniper's Nest overlooking Cottonwood Cove. The quest is "completed" once the player has opened any one of the metal boxes located on the ledge.

This quest is recurring: the quest will re-appear approximately every three days in the form of a new quest marker guiding the player to the cache. This will continue so long as the Courier's reputation with Caesar's Legion is primarily positive.

Cache contents
There are a maximum of ten boxes available on the ledge, split into two groups:

Five boxes are located on the west side of the ledge. These boxes are labeled "Legion Dropbox" and contain Legion Denarii totaling 235 in count between the five boxes. All five boxes will always be present

As many as five boxes are located on the east side of the ledge, overlooking Cottonwood Cove, and are labeled "Legion Supply Cache". At least one of these boxes will be present; the number of boxes depends on how well liked the Courier is by Caesar's Legion, with a total of five appearing if the Courier has an "Idolized" reputation with the Legion. Loot in each box is randomized, but can be generalized as follows, in order of reputation:
 * 1) Basic ammunition and healing chems
 * 2) Basic ammunition and as many as 15 doctor's bags
 * 3) Basic to mid-grade ammunition, mid-grade armor
 * 4) Random ammunition, random chems
 * 5) Random ammunition, additional .44 magnum and energy cell ammo.

Bugs

 * This quest cannot be obtained if the player has previously received the Caesar's Hire quest. Additionally, Caesar's Hire will not recur while the player has a positive reputation, despite this quest not being obtainable.
 * It is possible to permanently disable this quest if the player fast-travels away from the Disguised Frumentarius as he is approaching.
