Heaven's Gate

The Heaven's Gate is a craftable Hardmode magic weapon. On use, it fires a three-round burst of three heavenly weapons from behind the player in the direction of the cursor, similarly to the Sky Fracture. The heavenly weapons inflict the Holy Glare debuff on hit, dealing damage over time and causing enemies to receive 15% increased damage from all sources.
