Rescue Tandi from the Raiders

Rescue Tandi from the Raiders is a side quest in Fallout.

Detailed walkthrough
After completing the Stop the Radscorpions quest, exploring Vault 15 and waiting 2 days, either Seth or Aradesh will ask the Vault Dweller to save Tandi from nearby raiders, known as the Khans.

If the Vault Dweller talks to Razlo before leaving town, Razlo will sympathetically give them 2 stimpaks. If the Vault Dweller talks to Aradesh and agrees to find Tandi, he will give them a spear.

There are numerous ways to rescue Tandi:
 * Defeat all of the Khans and break her out.
 * Fight Garl in Unarmed combat for her release.
 * Purchase her from Garl.
 * Intimidate Garl for her release (45% Speech required).
 * Quietly kill the two guards at the rear of the building and pick the lock on Tandi's cell.
 * With a Luck of 9 (and male gender, and wearing leather armor or using a Stealth Boy), the raiders will mistake the Vault Dweller for Garl's father, whom he killed to take control of the Khans (50% chance). With at least 6 Intelligence and a Charisma or Speech check, the Vault Dweller can bluff Garl with this ruse and secure Tandi's release.
 * Use dynamite on the door to her cell.

The first and second methods of rescue entail a lot of risk, with the second method especially so should the Vault Dweller still be at a low level, as Garl is a highly competent brawler and is much more experienced than his men.

Tandi can be used as a party member if the Vault Dweller never takes her back to Shady Sands. However, since she cannot be given combat commands and doesn't appear to change her equipment she is of limited use. She also doesn't have comments for any area or event beyond just taking her home, whereas the other party members will comment on various areas, buildings and people throughout the game.

Rewards

 * 500 XP for freeing Tandi non-violently (such as the "threat" speech check") and 400 XP for returning with her to Shady Sands for a total of 900 XP.
 * 500 bottle caps
 * 2 stimpaks (optional)

Bugs
If the Vault Dweller has Ian as a companion, and fights Garl, he may get into the ring. If this happens, he will attack Garl; (Unarmed or by shooting as well) when Garl does not. Normally Ian is outside the ring and cannot help.
 * If the cell door is already picked and opened before this quest becomes active, Tandi will not be in the cell (all the same - upon going back to Shady Sands, Aradesh will thank the Chosen One for rescuing her) - this can prevent getting her as a fifth "companion".
