Monster Psyche Standard Base data
Field record
An Object Anomaly resembling an ordinary trash can. Decomposers of different appearances have different preferences for trash. When disposing of garbage, it's best to know their tastes.
In the field, Decomposer is logged as a normal Oddity roaming Hethereau, and the Hunter Association files it under threat classification II with standard clearance. Its poise is governed by the Psyche and Standard stagger families, so leaning on matching damage breaks its balance bar fastest and opens the cleanest burst window. Clearing it rewards loot drawn from the in-game sequence, detailed in the rewards table below.
