Desperate Measures

Head to Anachronia to speak with Mr Mordaut in the base camp.

Go north of the base camp, and down the two flights of stairs to the dragonkin gate. Do not begin the Agility course.

Dismiss any pets or followers and then speak with Thok or Charos.

Inside the flashback, go to Charos. Finish all dialogue before continuing else you will exit the flashback and have to start over.

Smash the feral dinosaurs.

Continue east along the path, attacking more dinosaurs as you go.

Talk to Laniakea and then follow her across the bridge. After Kerapac leaves, finish the conversation with Charos.

Uncover and excavate the dragonkin remains excavation hotspot that appears 4 tiles south and 3 tiles east of Thok and Charos to obtain a dragonkin device (damaged).

Restore the dragonkin device at an archaeologist's workbench.

Talk to Charos.

Excavate the orthen rubble spot, which appears about three paces north of him, to obtain a dragonkin tablet (damaged).

If you do not have enough orthenglass, you can destroy the tablet and excavate again.

Restore the dragonkin tablet at an archaeologist's workbench.

Talk to Charos.

Head to the Anachronia Dinosaur Farm (from the Manor Farm, go to the top floor of the manor and teleport using the mystical tree).

Speak to Hannibus next to Prehistoric Potterington.

Travel to the Nodon Hibernatorium on the north-eastern coast of Anachronia, east of the Herby Werby entrance and south-east of the Observation outpost (see map).

Enter the southern door next to Hannibus using the dragonkin device you restored earlier.

Talk with Hannibus inside.

Speak with Hannibus again to start a memory.

Eventually, one of the Nodon caretakers will walk to the south-eastern corner of the room. Wait for the Nodon caretaker to finish putting in the passcode on the pylon, and you will be able to cycle the symbols.

You must first click on the pylon in the shared memory.

Talk with Hannibus to exit the dream.

Cycle each of the three symbols outside of the dream until they match what you saw in the dream. Your character will interrupt when a symbol is input correctly. Continue that dialogue instead of exiting the chat box, otherwise, Hannibus won't recognise the correct sequence.

Re-enter the dream and start the shared dream again. This time, follow the other dragonkin outside.

Follow him until he walks to the door at the front of the ruins and speak a passphrase. Not being close enough to the door will cause you to miss the passphrase.

Speak to Hannibus again and exit the dream (you can lobby and log back to go faster). Return to the front of the ruins and enter the door with the passphrase you heard earlier (should be in the chat box).

Inside the front door, speak with Hannibus again to enter another shared dream. If the room is empty it means you actually do not have the right code, even if you cannot change it.

Ensure you rotated three characters on the pylon; one on the left, one on the right, and one in the centre. May need to zoom in to see. Hannibus should also be now standing in front of the door, he wasn't before. Each character will confirm a prompt once it is in the correct position. There will be 3 dialogue confirmations total.

Speak with Hannibus, next to a water pool, inside the dream to start a shared memory.

Skip the cutscene on Kerapac's device.

Attack Kerapac until he flies off or watch your party of NPCs try to fight him. It may take about 1 minute. No damage will be done to or by you in the fight.

Return and talk to Seren in Burthorpe.

Speak to Primrose located in the house by the Needle (far west of the Piscatoris Fishing Colony).

The nearest fairy ring is.

Memory strand can also be used to teleport to Memorial to Guthix, which is south of the house.

Talk to Primrose and exhaust all chat options (focus on finding the needles weakness). Your quest log should update to speak to Seren.

Return to Seren.

Make your way to Heart of Gielinor in the Kharidian Desert. (The Heart teleports can be used, or travel to Nardah using the magic carpet network and run south-west). Alternatively, the nearest fairy ring is, then run south.

WARNING: Due to a bug, Jas's eyes will be flashing incredibly fast depending on your FPS.

It's highly recommended to limit your FPS to 5 before proceeding if you suffer from epilepsy or other vision problems.

Speak with Seren outside the Heart.

Speak to Jas about Kerapac.

Speak to Jas about the Needle.

Ask for Jas' help then exit the dialogue. The Eye of Jas should be in your inventory.

Talk to Seren.

Return to the Anachronia base camp and speak with Charos near the lodestone.

After Kerapac turns up, speak with Thok to start the fight. You can't be wielding anything in your hands.

Follow the instructions set out when starting the fight with your team members (Hannibus, Thok, Charos, and Laniakea).

If you get the message "you need to finish speaking with Charos before you can start the encounter", you also have to change Charos attack type (just choose closest), then you need to move Hannibus one square away and move him back to his original place.

Keep them in their default positions, and stand two squares west of Charos. You should win without moving, but if you struggle then move your character around to get early hits on the bigger dinosaurs.

If you exit dialogue with Charos too early you may need to reset the instance by right clicking Thok and clicking Leave.

After the fight is complete, speak with Charos next to the lodestone. Go north past the Anachronia Agility Course and speak with Charos once more. The Measure should be in your inventory after speaking to him—if not, it may be in your bank; you will need to speak with Charos again before proceeding.

You have to use The Measure near Charos a total of four times in the ruined areas surrounding the volcano. He will speak to you automatically if done correctly. If anytime during this Charos disappears or you are unable to interact properly with him, log out and back in or try hopping worlds. Charos will be standing right at the spot you need to use The Measure at. When you arrive at one of the spots where Charos is at, place The Measure. After placing The Measure, it's unnecessary to fully finish speaking to Charos. Players may proceed to the next location.

The first location is a bit north of the entrance where you talk to him.

The second location is north of the lodestone. Start the Agility course, enter through the cave, cross the roots, and walk north till you reach the camouflaged jadinkos.

The third location can be reached by teleporting to the Anachronia lodestone, then head west past the bridge and north-west past the arcane apoterrasaur until you reach the dragonkin ruins. Alternatively, players that have unlocked the Orthen teleportation device can teleport to the third location.

The last location is directly east of the previous location, up a flight of stairs.

Prepare for combat.

Speak with Charos again (north of the base camp). (If he is not there, step into the room north of Thok and step out again. He might appear in the northern room, if so, place a measure in front of him.)

Enter Kerapac's laboratory. (An entrance will have spawned where you met Thok and Charos north of the base camp.)

Enter the correct codes into the pylons on the four corners of the area, as given in the image on the right. The codes are the same for all players.

The south-western room's solution is 2-1-4.

The north-western room's solution is 7-1-5.

The north-eastern room's solution is 4-1-6.

The south-eastern room's solution is 3-1-4.

Enter the room to the north that has now opened up and prepare for a battle with the black stone dragon. (If you die while fighting the dragon, it is a safe death.)

After defeating the dragon, talk to Kerapac when he appears.

Choose any chat option, and after the cutscene, the lab will start to collapse and you will get a timer on your screen and have to escape. When you hit a dead end, turn around or interact with a nearby character to continue. Failing restarts the escape.

If you get sent back out before talking to Kerapac or the escape sequence by logging out or being interrupted (such as conjures), you may re-enter Kerapac's lab to trigger the sequence again.

After escaping the lab and the following cutscenes, return to Seren in Burthorpe (requires 4 backpack spaces to collect reward).

Quest complete!

Players can upgrade their cosmic focus to the cosmic accumulator which provides 20% Sprite Focus instead of 10%.
