This page contains description of Fashion's Creed available in Assassin's Creed: Odyssey. You can unlock it by wearing a full legendary armor set.
An armor set consists of 5 pieces - headgear, chest armor, waist, gloves and boots.
Legendary (gold) pieces of armor found during the game can be part of different sets. The picture above shows an example of waist armor that is part of the Pilgrim Set. To unlock this trophy/achievement you need to wear five pieces of armor that are part of the same legendary set.
You can easily get this trophy by completing quests related to the Cultists of Kosmos, namely The Eyes of Kosmos. This quest is the easiest one out of all missions where you have to assassinate the Cultists.
To complete this quest you have to defeat five "lesser" Cultists - those that will help you identify Nyx (one of the Sages). Kill the last, fifth, cultist from this group to receive Snake Set.
Snake Set consists of:
- Viper's Hood
- Venom Gloves
- Scaled Torso
- Slithering Belt
- Noxious Boots
You can check the full set equipped in the attached picture.
