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