Are you trying to quickly kill the last boss in Spire of the Watcher Dungeon? Then you are in luck, as here we will go through everything you need to know on how to kill this boss efficiently and all the mechanics.

Destiny 2 is a popular looter-shooter video game created by Bungie, well known for its creation of the Halo franchise of video games. In this MMO RPG, you can select from three distinct classes and earn various weapons from raids and other activities. Additionally, you can complete some Dungeons and Raids to obtain some exotics gears and weapons.

However, if you want to obtain some exotic gear and high-power-level armor, then you might need to run some dungeons. Dungeons are also the most efficient way to farm materials and other essential items such as enchantment core and enchantment prism.

Although dungeons are not that hard to complete, the bosses can be a pretty nuisance if you don’t know the correct mechanics. So don’t worry; in this guide, we will go through a step-by-step guide on defeating Persys, Primordial Ruin, so that you can complete Spire of the Watcher Dungeon without a hitch.

Who is Persys, Primordial Ruin?

Before discussing how to defeat Persys, Primordial Ruin, let’s talk briefly about what it is or where to find it. Persys, Primordial Ruin, is the last boss of Spire of the Watcher Dungeon, and since it is the last one, it is a pretty tough guy too. If you want to face it solo or with average teammates, you will have difficulty defeating this guy.

Although it’s not impossible to defeat it solo, it would be much easier to complete this dungeon with some good teammates and some good gear. Also, it is good practice to watch some videos or read some articles about any new dungeon and its mechanics so that you can have a good sense of what to do and how to do it.

After dropping down from the final and the fifth room, you will encounter the last boss fight. This encounter is going to be a combination of the two different circuit mechanics, and you’re going to see yellow wires and red wires. So while the boss is chasing you around and utterly immune to damage, you need to complete these connections.

Put on a void damage resist and try to move around the map and avoid this guy because it smacks a little hard. Since you will need to kill a Minotaur, get the buff and then shoot the five different red wires, you should focus on them instead of the boss.

The first four are easy to find, and there’s one more node on top of the middle doorway. Once you shoot all these five red wires, the door will open and lead into the next part of the encounter. Once that main door is opened, it will also open two previously closed nodes for the yellow wire circuits.

So there are four different yellow wire circuits. Initially, all four are closed, and two random ones open up when that metal door is opened, and then you need to complete those two newly opened yellow circuits. So follow them all the way to the fuel rods that are located in the back of this Arena.

When you activate two different fuel rods, you will get a notification on your screen that says reactor surge imminent seek safety, and things will start blinking. It looks like it’s going to explode, but if you leave this fuel Rod area, the boss will stand near here, and nothing will happen, and it will return to what it was.

Once you get this warning, you must head back out and shoot the five different red wires once again in quick succession. This is going to close that main door that you previously opened. Then it will become a trap, and that reactor area will be closed and kill anyone inside, so make sure you get out before there. Still, it will strip the immunity Shield off of the boss, and then you can enter into a DPS phase.

That is the mechanics of getting to a damaged phase. Once that ends, it’s the same process of opening that middle door by shooting the red wires that will let you complete two of the yellow wire circuits. The two fuel rods go down. Then get the boss in that back room. You get out of the reactor room and close that door and then enter into another down trace. Do this as many times as you need to kill the boss eventually.
