How to unlock the Acidification achievement in Styx: Shards of Darkness - Definitive Guide
You can craft an acid trap with 3 Iron Ore and 2 Unstable Spores. Sometimes you are able to find an acid trap in a mission. Once you have one in your inventory, find any guard that travels a path. Place an acid trap along their path via then do a Quick Save. Wait until they croak and the circular save icon stops spinning in the top right of your screen, then Load Last Game from the main menu to do it again. The trophy will unlock immediately on the 5th kill.
Acid traps are small, deployable bobby traps that, once stepped on, release a deadly stream of acid at the victim, dissolving their body immediately. Unlike most items within the game, acid traps are not typically found throughout the missions; you must unlock the Acid Trap skill in the Alchemy talent tree in order to craft them.
Once you have a few acid traps available in your inventory, simply find an enemy guard who has a set patrol. Place the trap on the ground where the guard would normally walk and once he/she steps on it, they will die. You can repeat this process four times on the same guard if you choose to create a manual save before they step on the trap. Once you have killed five guards in this manner, the achievement will unlock.
