There are three of these power puzzles, one at each pyramid power tower in the Ancient World, and they are all solved with the Shock Rifle. Shoot a node and the nodes it links light up — the whole puzzle is a graph, and the trick is knowing which node to shoot.

What the Shock Rifle does to a node

The rifle is found in the underground lab of the house with the overgrown eyes and the deer outside it, on the island you reach through the dome-shaped teleport buildings. The rifle is lying right next to a skeleton down there, and the Blue Seal Breaker is in the same lab.

The mechanic in one line: shooting a node lights up the nodes it is linked to. The nodes are the balls on the wall, and the links between them are what change when you fire.

Both the region and the two items are covered in the Ancient World guide.

Queen's Domain electricity puzzle: solve the endpoint first

The key is the endpoints — the nodes linked to only one other node. Those are the nodes that trigger only two balls when shot, and they are what you are actually aiming for.

The intended method:

  1. Clear everything around an endpoint first, so that only the endpoint balls are left.
  2. Shoot the endpoint.
  3. Only two balls go out, and the puzzle moves on to the next stage.

Two of the three puzzles are relatively simple once you see this pattern. The third one is the outlier, and it is covered in the next section.

One practical note before you start: reaching one of the pyramids needs all five air dashes, unless you use the Cestus plus three. The gem count is in the Wind Gem guide.

The hardest of the three towers

The hardest puzzle is the one at the tallest isolated tower, and it is the one that feels like a Rubik's cube.

Two things to work with:

  • Start with the guaranteed nodes — the ones linked to only one node. Get those out of the way first.
  • Then find the place in the web where you have flexibility: a spot where you can hit four nodes to one side, three in the middle and four to the other side, and work out which of those solutions that specific spot needs.

There is also a triangle section of the graph with its own rules:

  • Hitting the top lights three nodes.
  • Hitting one side turns those three off and lights one node on that side.
  • Hitting the other side lights the triangle plus a node on the other side.

Why these three towers are the wall they are in the late-game plan is in the difficulty guide.

There is no reset button

This is the part that turns a five-minute puzzle into a twenty-minute one:

  • The state does not reset when you rest or reload.
  • The only way to undo a shot is to hit the nodes again.
  • The Shock Rifle therefore has to recharge between attempts, and it recharges slowly.
  • A tool can be equipped that helps the energy recharge faster, which turns the grind from painful to merely tedious.

So plan your shots before you fire. Once all three pyramids are offline, the big bridge to the castle opens, and the route through Siraatsu Castle is in the Ancient World guide. The recharge rules are in the stamina guide.
