The game says it can be crafted in a Fabricator, but on my single player PvE world, it had to be created in an Obelisk.

In Ark Ascended & evolves this engram is unlocked after completing ANY boss fight(minus Moeder master of the Ocean), you must craft it at an Obelisk or Supply drop. Crafts anything 12x faster. Takes 1 element to run for exactly 9 minutes on official PvE. Has 600 item slots and is unusable by anyone without the engram learned. It fits on a single foundation but needs a 3x3x5 to fully conceal.
