Complete Dealic Understanding on your Cypher Research Console. Pocopoc will then offer you the quest Core Control, which unlocks the ability to interact with coreless automa throughout Zereth Mortis.

Equip a piece of Cypher Equipment with the Zereth Vision stat before farming — this is found on cloth shoulders, leather shoulders, mail helms, and plate chests with the cypher equipment tag. This allows Pocopoc to take control of coreless automa without actually consuming his energy.

Fly to Zereth Mortis and search for coreless automa. Known Coreless Vombata spawn locations include at 33.2, 56.2, at 37.2, 37.6, and at 37.8, 47.2. Note that Coreless Guardian does not count toward this achievement.

To speed up locating coreless automa, create a macro that targets Coreless Vombata, Coreless Helicid, Coreless Scarabid, Coreless Tarachnid, and Coreless Geomental in sequence, then keybind it and spam it while flying around Zereth Mortis.

Land before interacting — neither you nor Pocopoc should be flying when you order him to take control, or he will not enter the automa and you will receive no progress. Right-click a coreless automa to interact with it, then order Pocopoc to take control. Wait until the automa is actually following you before ordering Pocopoc to leave, then move on to the next one and repeat until you reach 100 takeovers.
