How to Get a Destitute Smuggler Decoration
Cartel Pack Decorations
The Destitute Smuggler decoration can be dropped from Acolyte's Shadow Packs, which were released on the Cartel Market and bought with Cartel Coins. Cartel Packs, including the Acolyte's Shadow Pack, include a random selection of items from the Acolyte's Shadow collection of items. You aren't guaranteed to get a Destitute Smuggler decoration from a Acolyte's Shadow Pack, but it is one of the few ways to get a Destitute Smuggler deco apart from buying it on the GTN from another player.
If you're looking to get a Destitute Smuggler, the easiest way to get it is to head to the Galactic Trade Network (GTN) in SWTOR and buy it with credits from another player. If it's very rare and not available on the Cartel Market, you could try buying from the GTN and hope you get it.
