The concept was first introduced to Destiny 2 in 2019 alongside the arrival of the 'Armour 2.0' revamp with the Shadowkeep expansion as part of Universal Ornaments, allowing you to adopt the appearance to only a select few cosmetics.ĭeveloper Bungie rolled out this feature in full with the Armor Synthesis system as part of the Season of the Splicer, allowing you to fully customise your appearance. Transmog - short for 'transmogrification', and also known as 'tmog' by the community - is a term used in online games such as MMOs to change the appearance of an armour piece to another. Destiny 2's transmog system is one of the most anticipated features coming to the game.
