How to unlock the Savage! achievement in Moonlighter - Definitive Guide
However, there is a pretty easy, albeit still time-consuming, way that you can farm this fairly idly. In the tech dungeon there is a chance that you will come across the room in my attached video, which will allow you to just tap A to repeatedly OHKO slimes ad nauseum thanks to the enemy that can re-spawn enemies.
When you've had all that you can take in one sitting, just use a town portal in the adjacent room. This will allow you to return later and farm this across multiple sittings. I as able to get 1,500-2,000 kills an hour while watching Cobra Kai season 2 and mindlessly tapping on the A button to the rhythm of enemies spawning.
You can do this completely idle, all you need to do is line up your pet so that it is directly across from the slime. Then every time the slime respawns your pet will kill it for you. I used the Golem Turret to get the kills for me.
Here a link to a screenshot of the room:

Sadly you will need to grind quite a bit for this achievement. After getting 1000 kills in each of the four dungeons and getting to the third floor of each ten times, you'll likely still need at least 5000 more kills, if not the full 6000 difference. Simply return to the first dungeon and slaughter everything you see. Be sure to use all the waves of a horde room if you find one to increase your count.
**Glitched**
It seems the counter for this resets when you exit the game and/or does not track properly. The work around is to do this all in one session.
This will take you awhile, as you will have to actually grind for this trophy as you will not complete this naturally throughout the game. You will at least have 4,000 kills by going for the other kill related trophies, so you will have to continue to grind out the rest of the kills. Unfortunately, there is no tracker to look at for how many kills you currently have.
And it seems that update 1.13 fixed this trophy, because it crashed for me only after installing it.
