Magic Circle

Rancor is a post-Moon Lord magic weapon. It is the exhumed form of the Burning Sea. It creates a magic circle a set distance away from the player. After 4 seconds, the magic circle fires a large laser beam that pierces infinitely. Upon contact with solid tiles, the laser spawns dust, fog, and lava at the impact location. Additionally, damaging arms emerge out which deal 66.67% of the laser's damage, along with large cinders which fly out and deal 33.33% of the laser's damage. Both arms and cinders can also damage the player for 160-180 / 320-360 damage. Enemies struck by the laser beam are inflicted by the Rancor Burn debuff, which cause them to disintegrate into ashes on death.

Its best modifier is Mythical.

Rancor fired at a row of three grounded Target Dummies, then at a wall.


  • The word "rancor" means bitterness or ruthlessness.
  • The magic circle that the weapon summons is based on the Human Transmutation Circle from Fullmetal Alchemist.
