NOTE - This is not a tutorial on the mechanics of the fight. This is a strategy guide to get 110+ Skulls and defeat calus in one cycle. I am writing this with the assumption that those reading already have a general understanding of the mechanics of the encounter. Set Up - Have 2 people go back to the throne room and clear ads, have the other 4 stay in the purple realm. With 4 people in the realm everyone will still need to call out their symbol, 2 people will call out the same symbol because there are only 3 total that will be shown, so the people in the throne room will have to pay extra attention. The reason why you can kill so many Skulls with this set up is because you will have 4 people in the realm shooting Skulls. (This will only work if you have 2 people who are Very (VERY) good and will be able to handle all the ads and still kill the psions in the throne room. If you do not have the most skilled players, do the normal strategy although it will take longer and thus leave more room for errors. Which means more wipes and more time consumed. Strategy - When you finish Punching the psions and the Skulls start coming out, although it's common sense it'd like to emphasize this: The 2 in the throne room need to wait as long as possible to take down calus' shield, get it down to low health but leave it alive until your screen turns white and you can't even see anything. If you wipe trying to get the timing right, it's ok. All you need to do is get it done correctly once as it will be trivial to kill calus in the first cycle. What my group did (and what I recommend) is when it came to the damage phase: Start on the left platform farthest from Calus and rotate clockwise. For specifics and to max dps (there is probably a better way to max dps, feel free to comment it, however with 110 Skulls it is not that important) here was our strategy. We had: 2 nightstalker hunters 1 arcstrider hunter 2 Warlocks of whatever class And some other guy it doesn't really matter On the first plate, we all jumped on and did normal dps, not using any supers or warlock damage rifts On the second plate 1 of the night stalkers tethered calus and a warlock put down his damage rift On the third plate the arcstrider jumped off and cleared ads while the other 5 continued dps On the fourth and last plate, the remaining nightstalker tethered calus and the other warlock dropped his damage rift. For weapons I'd recommed the cold heart, however it does not really matter that much as with 110 Skulls you will be shredding calus and will have him down on the first cycle, with time to spare. I'd like to mention that I got in a group of all randoms from LFG last night, and we defeated calus with this strategy second try. (First try some guy died in the realm idk how, I think maybe he jumped and got sucked in) I really hopes this helps you all as I know that Calus can be a big pain to defeat. I'm looking to run the raid again tomorrow (reset Tuesday) If anyone is interested with doing it with me feel free to add me on Xbox GT: AIRdawg dude Or join my clan The Baiters I'll be running people in my clan through the raid all week.
