Not to be confused with the Royal Scepter, a vanity accessory sold by the Princess.

The Resonance Scepter is a Hardmode, post-Plantera magic weapon that creates a glowing pink circular projectile at the cursor's location, which expands and then collapses into sparkles over the course of 1 second.[1] There must be a clear, unobstructed line of sight between the player and the cursor's location for the projectile to be summoned right on the cursor, otherwise, the projectile will be summoned upon reaching the first solid block. The Resonance Scepter has a 1/8 (12.5%) chance of being dropped by the Princess.

Enemies within the projectiles will be rapidly damaged[2] and knocked back away from the player. There is no limit on how many times a projectile can strike enemies, but the damage of the projectile will be reduced by 2% after each strike.[3] The Resonance Scepter is held in the player's hand and also sparkles while it is used, emitting pink light.

Its best modifier is Mythical.


A player using the Resonance Scepter against Target Dummies.


  • This is a powerful magic weapon, but it requires every NPC to be present as that is the requirement for the Princess NPC to spawn.


  • The Princess uses the same attack when threatened by enemies, although the scepter itself is not shown.
  • The Resonance Scepter can be considered an indirect upgrade to the Inferno Fork as it is nearly functionally identical, has higher stats (besides knockback and the Hellfire debuff), and instantaneously reaches the location the player aims at. The Resonance Scepter's projectile can also pass through blocks and in midair, which the Inferno Fork cannot do aside from exploding upon making contact with a target.
    • It can also be obtained before entering the Hardmode Dungeon, making for an easy upgrade from their current weapon with little effort if the player has obtained all NPCs so that the Princess can arrive immediately after killing Plantera.


  • Desktop No longer drops pre-Hardmode, if the Princess is somehow obtained pre-Hardmode.
