Location and Uses
Out of all the many Weapons, the Jeweled Dagger is the strongest type of Dagger, dealing 4 damage to a single enemy standing in front of Cadence and Zelda. It functions identically to the Kokiri Sword, and if the Kokiri Sword is obtained before the Jeweled Dagger, it'll automatically end up in Cadence's and Zelda's inventory. Like all other Jeweled Daggers, it can only be used by Cadence's and Zelda.
In Crypt of the NecroDancer, the Jeweled Dagger retains the same role as the strongest type of Dagger within the game, although it deals a whopping 5 damage to enemies as opposed to the one that appears in Cadence of Hyrule.
