In The Ghosts mission, the Solar Scythe is in the final boss arena on Savathûn’s Throne World. You usually have to shoot the three glowing crystals / resonant nodes in the room first , and then the Scythe spawns in the center of the arena near the fight area.

Fast route

  1. Progress to the final encounter in The Ghosts.
  1. Look around the outer parts of the boss room for three hidden glowing crystals or nodes.
  1. Destroy all three.
  1. The Solar Scythe appears in the middle of the arena, then you can pick it up and use it for the triumph.

What to watch for

  • It can be easy to miss because the crystals are tucked around the room edges.
  • Some players report the Scythe appearing in a side room or behind a pillar depending on timing or phase, but the reliable trigger is still destroying the three nodes in the final arena.
  • If you’re doing the Relics of the Past triumph, make sure to get kills with the Scythe before finishing the mission.

TL;DR: Go to the final boss room in The Ghosts , destroy the three crystals/nodes , and the Solar Scythe should spawn in the center.
