Might be obvious to some, less so to others: With the release of the Challenge Mode of Torghast, The Twisting Corridors, you can just queue layer 1 and reset until you have the part that you need for the achievement.

You don't have to wait until the week that it's up, as Twisting Corridors is 3x a randomly selected part of Torghast (can also be 2-3x the same in a row, as I've had the Soulforges twice in a row, floor 7-18).
You can queue layer 1, enter, check out which part you're in and compare it to the list of powers/mobs over on the [item=170540]'s page's comment section.
If you don't need that part, exit behind you, requeue; Rinse, repeat.

Once you're done with the first 3 floors, you can buy your Ravenous, and use it on floor 4. Turn around and leave. Or finish, go up a floor and then leave, whatever is faster.
If you need a lot and you have great powers, you can also just go to floor 7 and see what it continues into before leaving.

I bought a ravenous anima cell and was saving it while looking for a mob that I didn't have credit for yet. When an anima cell appeared out of a vase, I was offered the Mawrat Harness power and selected it. It gave credit towards the achievement even though I did not specifically use the ravenous anima cell to obtain it.
