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