Before you can start Spire of the Watcher, you must visit Ikora Rey in the Tower and pick up the quest, Ares Desperado. You must also have completed the Witch Queen introductory quest, The Arrival (free to all players). With the quest in your inventory and the Arrival completed, you can launch the Spire of the Watcher via Savathun’s Throne World. Look for the dungeon icon next to the Enclave.

Reestablish Power

The first encounter has a single goal: reestablish power. This is accomplished by defeating Conduit Minotaurs, acquiring the Arctrician buff, and shooting nodes in the correct sequence to complete a node circuit.

  1. Defeat Conduit Minotaurs and stand in the pool they drop to get Arctrician
  2. Follow the power cables from the center hatch to the generator
  3. Shoot the first node at the generator, follow the power cable to the next, shoot it and repeat until you reach the last one
  4. Repeat this process until all four nodes are activated

When you first enter this small town area, locate the large hatch and the four power nodes. The cables connected to them lead to four generators. The starting node in a sequence has white arrows flashing beside it and is found at the generator.

Conduit Minotaurs will spawn that drop the Arctrician buff when defeated. This lasts for 30 seconds and allows the activation of the nodes. Start with a node at the power generator and follow the cable along to the next one. The nodes must be powered up in sequence, skipping over a node or activating the wrong one will cause it to deactivate after a couple of seconds.

Activating all nodes along a power cable will lock in an Arc node at the central hatch. Once all four nodes are activated you will be able to progress deeper into the Spire of the Watcher dungeon.

During this fight, Cyclops will spawn along the ridgeline while Goblins and Harpies will swarm the middle.

Ascend the Spire

As before, Conduit Minotaurs will drop Arctrician buffs that are used to charge the nodes. Follow the cables along, charging nodes, and defeating Minotaurs as you climb the tower.

  1. Defeat Conduit Minotaurs for the Arctrician buff
  2. Activate Arc nodes in sequence to charge elevators
  3. Climb the spire to the top

The Ascend the Spire encounter is basically the exact same as the previous one, albeit with the added challenge of climbing the spire. Locate the starting nodes, defeat the Conduit Minotaur for its Arctrician buff, and start powering up the cables. Follow the cables as they wrap around the spire.

Once a set of nodes have been charged, an elevator will take you to the next section. Repeat this process until you reach the top and find your reward chest.

Akelous, the Siren’s Current

The first boss fight of the Spire of the Watcher is against Akelous, the Siren’s Current. Arctrician buffs are used once again to charge nodes, this time sending the current out to the ends of the boardwalks to activate a fuel rod. When all four are activated, Akelous’ eyes can be damaged and then its core.

  1. Defeat Conduit Minotaurs and take the Arctrician buff
  2. Charge up the nodes starting in the middle and going out to the fuel rods
  3. Shoot Akelous’ eyes and then its center mass
  4. Repeat until Akelous is defeated

The arena where you fight Akelous has a central area and four boardwalks that stretch out to fuel rods. In order to reach a damage phase, the nodes must be charged starting at the center. Locate the Conduit Minotaurs, defeat them, take the Arctrician buff and start powering up the fuel rods.

When all four fuel rods are activated, Akelous will go to one and a damage phase will begin. You must destroy its red eyes before its central housing becomes vulnerable. Up to 50 percent of its maximum health will be damageable per cycle.

As the damage phase ends, Akelous will perform a massive concussive blast, throwing players back and potentially off the edge. Prepare for this by slipping down into the boardwalks or using abilities to get back to safety.

Persys, Primordial Ruin

The final boss in the Spire of the Watcher dungeon is Persys, Primordial Ruin. Like the other encounters, Arctrician buffs are used to power nodes around the arena. This time, the goal is to activate a reactor core purge, which will make Persys vulnerable.

  1. Defeat Conduit Minotaurs and collected Arctrician buff
  2. Activate nodes to begin the reactor core purge
  3. Retreat to the safe room, activate the nodes on the pillars, and the node above the door to close it
  4. When the door reopens, damage Persys and then repeat the process

Tip: Red cables control the door, yellow cables power the reactor.

The arena fight against Persys, Primordial Ruin is split into two sections: a reactor room and a safe room. The goal is to use Arctrician buffs to activate nodes, beginning a reactor purge. At this point, retreat to the safe room where you can activate the nodes on the pillars and above the door to seal Persys in. Once the reactor purge is completed, the boss will be vulnerable for a short time.

Start by clearing the room of enemies. Once the Incarcerator Hydras are defeated, the Conduit Minotaurs and other enemies will spawn. Get the Arctrician buff from the defeat Minotaurs and then shoot the nodes on the inside of the pillars and the node above the door to access the reactor room.

When the main door to the reactor opens, two nodes on the outside of the pillars will open. Locate these nodes and use the Arctrician buff to create a charge from the safe room into the reactor room. With two reactors activated, text will appear on-screen stating: Reactor Purge Imminent, Seek Safety. Bait the boss into the reactor room and then retreat to the safe room.

Use the Arctrician buff to activate the nodes on the inside of the pillars and then the last one at the apex of the door. This will seal Persys in with the reactor. Once the purge completes, the doors will open and Persys will be vulnerable. If Persys is not in the reactor room during the purge, you will not remove its shield.

Repeat the whole process until Persys is defeated. This is certainly one of the easier boss fights in a Destiny 2 dungeon with the only challenge being the small rooms and Persys stomping around. 

The Spire of the Watcher dungeon is going to put up a decent fight the first time players dive into it in Destiny 2. However, it's got some cool loot to earn and is one of the faster dungeons to complete, so expect to be diving back in rather soon! Take a look at our featured dungeon schedule so you know which of the other dungeons will earn you some Pinnacle gear (or Artifice armor).
