As of this week's reset, the previously datamined Pocopoc Model Customization items have been hotfixed into the game! You are now able to collect items to customize your Pocopoc's appearance. These items have a chance to drop from Zereth Mortis content, and we have a list of all currently known locations below! Once you obtain a Pocopoc customization, you are able to customize your unit in Exile's Hollow, via the Pocopoc customization console at the left-side portion of Firim's cavern. Presumably, you need the Cypher of the First Ones customization Visial to loot Pocopoc customization pieces.
