How to Get Dynamo Lantern

Astral Orrery.

Best use cases

  • Use Dynamo Lantern for resource routing, exploration comfort, and puzzle or traversal moments that need a specific tool.
  • Treat its 3 Joule cost as a safety trade: spend when it prevents damage, saves a long chase, or confirms a route-critical hit.
  • Best fit: utility loadouts that need Winds up, then throws the lantern out on a chain a few tiles ahead, delivering several large electric bursts at its apex..
  • It is strongest when the Sidearm solves a concrete route problem: a flying target, awkward switch, dangerous approach, or cleanup check that would otherwise slow the room down.

Route notes

  • Location/progression note: Astral Orrery.
  • Refill and test the timing near an Underlab before using it in a long cleanup route.
  • Pair it with a weapon that covers the opposite range, so failed shots do not leave Mina without a safe punish.
  • If the route has multiple refills, spend it more freely; if the next refill is uncertain, save it for hazards that reliably cause damage.

Tested notes

  • Current metadata tags it as Utility and affects Sidearm, Passive Effects.
  • Extra Stat Level metadata: Attack 0, Defense 0, Sidearm 3.
  • Recheck exact Joule cost and hit behavior in-game after patches before using this page for strict routing.

Common mistakes

  • Spending Joules for damage when a basic weapon hit would be equally safe.
  • Forgetting to swap Sidearms between exploration, boss attempts, and cleanup routes.
  • Building around the tool before confirming that the current room actually rewards its range, safety, or utility.
  • Treating every shot as DPS instead of asking whether it protects routing rhythm, resource safety, or a difficult movement line.
