After 2-3 hours of play, Melodi tags along as a camp NPC. Some NPCs that tag along will offer wares and various goods. Melodi does this, but eliminates the pesky need of having to pay for them since she is, after all, Ronan's girlfriend. She's not going to make her boyfriend and his sister pay for things, is she?
After Melodi shows up at camp, she proclaims that she has some items for you that you can take off of her at your leisure. These items are completely random, so you never know what you're going to receive from her. Initially, Melodi has three items to give you. As you progress, her "stock" will gradually increase. The number of items Melodi has to give away is simply controlled by a variable, and various things the player does throughout the game will increase that variable by 1. Do a side quest in a town? Melodi has an additional item to give away. Clear a dungeon? Melodi's got more goods. As a result, she will be a steady source of free items throughout the entire game.
