Liquen dagger

If you keep nagging Nkaanmykiunsuns, she will throw this dagger at you. With high agility, you might even be able to catch it and steal it instead of it slicing your hand. Doing so will lead her to demand you to return it, or at least sell it back to her when talking to her the first time. This dagger currently has the highest player-obtainable pierce damage attack card in the game.
