Lucky Harith

Lucky Harith is a Caravan Merchant in Fallout 3. He is armed with a Combat Shotgun and has a cap, goggles, and a yellow mechanic's suit. Lucky sells weapons and ammo and also offers repair services for a fee. He also carries one set of Shishkebab Schematics. He follows a trade route that begins and ends in Canterbury Commons. Lucky's local inventory can be found in the footlocker in Uncle Roe's house. The key can be recovered from his corpse.

Unmarked Quest: Merchant Empire
Initially, Lucky Harith has a repair skill of 20, but after talking to Uncle Roe for further Caravan Merchant investment, his repair skill jumps to a maximum of 70 (allowing him to repair items to a maximum of 82%). Note however that his actual skill is 5% lower, since he is wearing a Red Racer Jumpsuit. After the second investment, he will reward you with a Mini Nuke as a gift of gratitude.

Location
Lucky Harith appears outside of frequent stops every time you fast travel to that location, go through a loading screen to that location, or wait at the site for a few hours. A good way to find him is to fast travel to Rivet City and go down the metal stairs. If he isn't there, wait for one or two hours so a merchant spawns. If the merchant isn't Harith, wait for one or two hours again. Repeat until you get Lucky to spawn.

Trivia
If you ask Uncle Roe about Lucky Harith he says that Lucky is also a very good martial artist, however, Lucky does not appear to have any Unarmed fighting skills.

Bugs
It has been reported on the 360 version for Doc Hoff and Lucky Harith to be found dead at Arefu every time a new game is made.
