First reward
The Westar 31B Ice or Acid pistol schematic (reusable schematic)
Second Reward
Charred Krayt Backpack
In order to get this backpack you must drop all skills that use skill points – 250 point must be available before you start the Triple Krayt quest.
The backpack makes the Mandalorian quest line easier to do by increasing reputation gained and reducing the effort required to do some missions.
This backpack also acts as a key in the Mos Pelgo Mines without it you would need to loot keys from mobs to unlock the way through this is a very slow process.
Third Reward
Full set of Mandalorian amor appearance schematics (one time use) You will also receive a Jetpack this will be consumed upon completion of the exit quest.
These schematics are just one way to get Mandalorian armor an Armorsmith can use these schematics to craft a set of armor they will also need the armor segment schematic from the Death Watch Bunker one segment schematic for a mini suit two for a full set.
Armorsmith can also craft this armor in the DWB using Reforged Bounty Hunter armor
You can equip the helmet at Mandalorian Apprentice you will need to have the Death Watch Initiate box to equip the full set.
Master Bounty Hunter, Master Commando, and Master Ranger can also equip Mandalorian armor.
Final reward
After you complete the exit quest you will spawn in a bunker be sure to talk to Din Djarin before you exit the bunker.
He will give you this trophy as well as a schematic for the Amban Sniper Rifle (we believe this is one time use)
