Just Trying to help people out. Feel free to ask me any questions as I noticed a lot of people are struggling on this fight. 1. Don't kill psions when they first pop up together. They drop heavy ammo but for each one you kill it spawns a yellow bar. 2. Teams of three into projection realm and throne room. BE QUIET AND COORDINATE so you can hear your call outs. It is the biggest thing for that fight. Have someone call out first, second and third. But quickly. 3. Have a runner in throne room grab the correct scion that wasn't called out while other two focus adds. If the runner is locked down make sure someone close can grab it. Throne room also needs to lookout for the random AoE when Calus snaps his fingers. It will be a big giant exploding sun. RUN AWAY! 4. People in projection realm should shoot across from eachother to kill psions that the other person cannot see. For example if you are on the left shoot right. Vice versa. Once the correct psion was killed in throne room you can see the next purple barrier appear in front of you...jump over your current purple barrier and get set at the next one. A good technique while trying to avoid being thrown over the little purple barriers for no reason is to crouch and hold back on your joystick. It will cause you to move slower and have a bit more control. Also...watch out for the big obvious death ramps and dips in the floor. 5. Bring auto weapons (sweet business, coldheart) and a healing rift to collect skulls easier for force of will in the projection realm. Those two and fusion rifles, including Merciless, are also great for boss damage. Rockets with cluster bomb are amazing for boss damage I use Sins of the Past (raid RL). 6. When the sun pops up above his head don't start shooting it until you have force of will x35 to x45 depending on dmg output. This will get you to x60+ easy. (Alternative you can lower his health immediately then stop and when you hit around x70 go in for the kill) 7. Come up with a pad rotation for damage phase and WAIT FOR EVERYONE to get back to the throne room to jump onto first pad. Maybe do a countdown to get onto first pad when everyone has returned. For example my group went bottom right pad to top right to top left to bottom left. AS SOON AS HE STARTS TO RAISE HIS HAND OR HIS GUN MOVE TO NEXT PAD OR YOU WILL DIE. 8. Use tethers or empowering rift and have hunters run golden gun for big dmg output. Primarily on the pads closer to Calus so you can output best accuracy and damage on his weak spot. 9. Repeat this process and you should have him down within 5 attempts. ALSO when you kill him remember there is a final kill phase. Pop some supers, Don't stop shooting and finish him off. Good luck Guardians! 😃 ...and as always...Praise the Sun! ☀️ \[T]/ ( ) \ / (Credit to Touchdown FSU13, Hurphy, contra_reality, mer1in20, AStoryToScream, SupSrsRager for helping to make this guide perfect!)
