The Season of the Splicer brings a new customization system to Destiny 2: transmogrification. The system allows you to change armor pieces to look like other armor pieces, giving you a greater degree of cosmetic control of how your Guardian looks. But the transmogrification system, called Armor Synthesis, is a pretty dense and confusing one. It requires you to gather and use new kinds of currency to buy new bounties and centers on Ada-1 in the Tower.
Working through the Armor Synthesis system requires you to work through a story quest, then take on new bounties to earn something called Synthweave. But how you get Synthweave requires a bit of work. Here's everything you need to know about Armor Synthesis so you can start transmogrifying your armor and customizing your look.
