How to unlock the First blood achievement in Loop Hero - Definitive Guide
This is likely going to be your second achievement in the game and should come very quickly. As you start circling around the path, right away you're going to start encountering slimes, the most basic enemy, that have a 5% chance of spawning on any path tile each day. You're not going to have any problem beating them and you should have your 5 kills in a couple minutes.
