Hunter: she'd keep a half dollar coin, a gift from her mentor. Heads, snipe that vandal; tails, it gets the knife. Titan: mp3 player. Plays nothing but Disney songs, which is all that was on it. Doesn't need it as a titan, but he/it found it on a dead terran child, and has developed an innate attachment to it. Warlock: nothing. As an Awoken, he's beyond the concept of emotional attachment.
