How to Get a Game Table Decoration
Cartel Pack Decorations
The Game Table decoration can be dropped from Dread Warlord PacksUltimate Cartel Packs, which were released on the Cartel Market and bought with Cartel Coins. Cartel Packs, including the Dread Warlord PackUltimate Cartel Pack, include a random selection of items from the Dread Warlord Ultimate Cartel collection of items. You aren't guaranteed to get a Game Table decoration from a Dread Warlord PackUltimate Cartel Pack, but it is one of the few ways to get a Game Table deco apart from buying it on the GTN from another player.
If you're looking to get a Game Table, 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.
