Planting items

 is the technique to give items to NPCs. It can be used to get equipment from characters that normally wouldn't be available.

Fallout 3
In Fallout 3, the trade is initialized just like a normal pickpocketing. Every transaction is checked and gives karma loss (if any), no matter in which direction the transaction went. The transaction can also be detected and blocked just like if you would steal something.

A Stealth Boy can be used if pickpocketing is too hard against that particular character.

To get someone to switch out their armor, it needs to have a higher DR value. (That means that you can't get everyone to wear Sexy Sleepwear, since it doesn't give a DR increase.)

The NPC will switch armor if you leave the area for a long time, or leave the area and do a save followed by a load and return to the area with the NPC again.

Example of items that are not available through other means:
 * Elder Lyons' Robe
 * Dads Wasteland Outfit
