Like many boss fights in Warframe, Ropalolyst can be difficult until you know what you're doing, then it's just a matter of executing the right strategy. Below we take a look at how to defeat the Ropalolyst, including some recommended warframes and weapons to take into battle.
The best load for Ropalolyst
Ropalolyst only takes damage from specific mechanics during combat, which means the majority Warframe's damage-dealing abilities won't be as useful. For this reason, we recommend taking a a tanky warframe that can survive the larger attacks of the Ropalolystlike Hildryn, Revenantor Inaros.
Warframes with healing abilities can also be used if you have high enough health and armor to not be one-shotted by Ropalolyst's laser attacks.
For your weapon, anything that can focus on specific points on the boss will work as sniper rifles. Essentially, any weapon you would bring to hunt Eidolons it will work well here. The ropalolyst is weak to radiation damageso be sure to modify whatever weapon you choose for this element.
Some weapons to consider are Rubico or Vectisor their Prime versions if you have them. Alternatively, if you have Voidrig Necramechhis built-in Exalted Weapon, the Arquebexis awesome for this fight.
You won't need to use your operator much for this fight, but using a decent booster will help.
How to beat the Ropalolyst
The fight against Ropalolyst will take place in a large, open arena, with three energy cylinders located to the north, east and west. When you approach one of these cylinders, using wires that connect the two platformsThe Ropalolyst flies to him and starts sending electrical charges down the wires.
Jump over them, using each of the four wires as needed. When you get to the platform, the boss will do it charge and then fire a laser at you. Avoid it standing behind the cylinderwhich by the way charges it.
Now go back to the main platform and use your operator's weapon to deplete Ropalolyst's shield. With the shield down you can now jump close to the bossa prompt will appear at this point 'Catch Ropalolyst'. Do it gain control over the bossthen point it towards the charged cylinder.
This causes the Ropalolyst land on the center platform. Now you will have to shoot the small metal canisters on his back. Just take it out one of these canistersso focus your fire on either the left or the right.
Once the container is destroyed, The Ropalolyst drops. Next, quickly move to the control panel near the arena entranceand interact with it fire the Terran Chargerwhich hits Ropalolyst with a massive laser.
If you don't activate the laser fast enough, the Ropalolyst will returnand you'll have to destroy one of his canisters again to get him back down.
Now you will have to repeat this process two more timesusing the two remaining power cylinders.
On the third fall of Ropalolyst, his the whole body will be vulnerable instead of just canisters on the back. Once you reduce the boss's health to zero, activate the laser a third time and the Ropalolyst will be defeated.
