Calus Bobblehead Dolls are scattered about the Derelict Leviathan destination in Destiny 2 Season of the Haunted. As of week 1, there are four available in the Castellum, the Pleasure Gardens, the Royal Pools zones, and the Sever-Shame weekly mission. The Castellum Bobblehead is locked behind a door that doesn’t always open, and the Sever mission Bobblehead requires you have access to the activity. Both the Royal Pools and Pleasure Gardens Bobbleheads are available at all times.
Once you pick up a Bobblehead, you can take it back to the Crown of Sorrow area of the H.E.L.M. and put it on display to the right of the Crown.
Castellum Calus Bobblehead Location
Two switches near five doors activate after you complete Tier 3 of the Nightmare Containment activity. From the Elykris boss area of the Castellum, head to the right of the central pillar and go to the far end of the level. The door you want is to the left of the entrance to the Royal Pools (Sun door) in an alcove.
The trick here is that the lever that opens this door doesn’t always activate after the final Containment. If it doesn’t open the first time you complete the activity, you’ll need to do more Containments until it opens. Once it does open, the Bobblehead is to the right of the chest.
Pleasure Gardens Calus Bobblehead Location
Head down into the Pleasure Gardens, and the first thing you’ll see is a large statue of Calus. Cross the area and head up onto the platform with the statue, then go into the space behind it. The Bobblehead is at the back of the statue’s base.
The Royal Pools Calus Bobblehead Location
Whether you make it to the Royal Pools beyond the Sun door via the Castellum or through the Underbelly from the Pleasure Gardens, head to the back-right of the area, and you’ll see a hole in the floor surrounded by corruption.
Head down into the tunnels until you reach an engine room. Turn around, and you should see another path leading deeper into the machinery. At the end of this shorter tunnel is a large patch of corruption and the Bobblehead.
Sever-Shame Calus Bobblehead Location
Make your way through the Sever-Shame mission for Crow, and you’ll eventually be chased by an invincible yellow bar Nightmare enemy. In the orange-lit area near where you put the heavy wrench, take the pipes on the right of the space up to the platform above you instead of jumping across to the lever.
The Bobblehead rests on some crates nearby.
Calus Bobbleheads Available in Week 2 of Destiny 2 Season of the Haunted
Week 2 of Destiny 2’s Season of the Haunted introduces only one new Calus Bobblehead, and you’ll find it early in the Sever – Reconciliation mission available near the end of the week’s Bound in Sorrow quest.
Sever – Reconciliation Calus Bobblehead Location
The Bobblehead in Sever – Reconciliation is located early in the mission in the pipes you explore just after placing the first amplifier. Traverse the pipe system until you reach the Egregore door, but do not go through. Instead, go to the very end of the hallway and enter the pipe there.
Go to the end of the pipe, which is light with a spooky red light, and turn left. The Calus Bobblehead will be in a corner there.
Calus Bobbleheads Available in Week 3 of Destiny 2 Season of the Haunted
As with week 2, there is only one additional Calus Bobblehead available in Week 3 of Season of the Haunted. Like Week 2’s bobblehead is quite easy to find in the Sever – Grief mission.
Sever – Grief Calus Bobblehead Location
After you load into the Sever – Grief mission, progress until you reach the first Ritual Amplifier deposit location near a door that wants desperately to open but just can’t find the energy.
Place the Amplifier and the door will open. Turn immediately to your left beyond the door and there will be a collection of boxes.
Head behind them and all the way around the corner, in a dark nook behind the boxes, will be the Calus Bobblehead.
Calus Bobbleheads Available in Week 4 of Destiny 2 Season of the Haunted
Week 4 introduced only one new Calus Bobblehead, as with weeks 2 and 3. This one takes significantly longer to acquire, and it much better hidden than the previous two.
Sever – Forgiveness Calus Bobblehead Location
You’ll need to make it almost to the end of the Sever – Forgiveness mission to get week 4’s Calus Bobblehead. In the tube just before the pipe leading to the Severance site, hop up into the orange-lit connector separating the entryway from the path leading to the Egregore spores and the final path to the site.
In the connector, jump up onto the set of protruding machines to find the Calus Bobblehead nestled near the fungus-encrusted ceiling.
Calus Bobbleheads Available in Week 5 of Destiny 2 Season of the Haunted
Week five saw another Calus Bobblehead become available. It appears midway through the week’s Sever – Rage mission, nestled in a dark corner.
Sever – Rage Calus Bobblehead Location
Progress through the mission until you reach the area where you need to Incinerate the Contaminant. Enter one of the side rooms is a large chamber with three fungus-filled pipes on the other side of the metal platform near the doors.
Drop down onto the earthen floor nearer the pipes and look beneath the platform. You’ll see the Calus Bobblehead waiting.
Calus Bobbleheads Available in Week 6 of Destiny 2 Season of the Haunted
One more Calus Bobblehead appears in week 6 of Season of the Haunted during the Sever – Resolve mission. Like Sever – Rage, this one is deep into the quest, not long before the final battle with the Nightmare of Dominus Ghaul.
Sever – Resolve Calus Bobblehead Location
Progress the mission until you are done with the Incineration step, then head back into the hallway with the large fans. A horde of Scorn will appear on a central platform. Clear them, then look up and to your left for a platform above you.
Jump up on the platform and enter the room beyond. The Calus Bobblehead is at the back of the room behind the machine in the right wall.
Place Calus Bobbleheads in the H.E.L.M. to complete the #1 Fan Triumph
The Sever – Resolve Calus Bobblehead is the last one. With it in hand, head to the Crown of Sorrow room in the H.E.L.M., to the greenlit chamber to the Crown’s left.
There will be quest markers throughout showing you where to place the bobbleheads. Once you’ve placed them all, you’ll complete the #1 Fan Triumph, which you can then claim as part of the Reaper title.
