Star Wars Jedi: Survivor has a ton for you to do off the beaten path and plenty of rewards for you to collect along the way. One of the rewards you can find on your travels are Priorite Shards, a new currency that can be used at several of the shops on Koboh. You can unlock a number of customisation options for Cal and his lightsaber, but there's one item at a particular shop that can feel like a bit of a gamble - the Mysterious Keycode at Doma's Outpost Commodities.
Unlike other items in Doma's shop, the Mysterious Keycode aptly doesn't tell you what it actually does. Considering the Keycode is ten Priorite Shards, which can be hard to find early in the game and is easily one of the more expensive items that Doma sells, you're going to want to know what you're spending your cash on. That's what we're here for.
How To Unlock Doma's Shop
First of all, we need to actually unlock access to Doma's Shop. The way to do so is pretty simple - all you need to do is progress far enough in the "Find Greez" questline on Koboh. Once you've reunited with Greez, you'll be sent down into the depth of Pyloon's Saloon to try and find some parts to fix the Mantis as part of the main storyline.
After finding Zee and bringing her to the surface as part of that mission, you'll be able to access Doma's shop and decide whether to buy the Keycode.
You'll find Doma's Shop situated across from Pyloon's Saloon. It's hard to miss thanks to its big blue door, but if you still find yourself having trouble finding it, then it's thankfully marked on the map as soon as you can access it.
What Doma's Mysterious Keycard Unlocks
Once you've gone into Doma's shop, you can take a look at what she has for sale. Most of it is pretty self-explanatory, like hairstyles and outfits for Cal, but there's one that's a little more unique - the Mysterious Keycode for ten Priorite Shards.
When you hover over it, Doma will note that it'll unlock a door in her shop, but that she's not sure what you'll find behind it. A little strange that she's selling entry to one of her own doors, but we'll go with it.
As we've said before, ten Priorite Shards seems a bit risky when you don't know what you're buying, but you should absolutely buy the Keycode as soon as you can. As it turns out, behind the door is an extra Stim Canister for Cal, which means you'll be able to heal one more time.
Considering how much trouble some players had with finding Stims in the original game, it's a great help so early in the game.
