How the heck are you supposed to get 10,000 raw metal?!

5000 metal weight- 5000 kg 😐

1 tek replicator weight- 4 kg 🤔

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.

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.

You only can craft it after defeating a boss

It cannot be crafted in fabricator on single player mode.

Mine just started killing any tame i put in a specific area near it, im in the desert oasis temple thingy on Ragnarok Ascended
