Destiny 2's Vexcalibur: Expert Authorization Override And Mysteries Guide

Destiny 2: Lightfall's Season of Defiance introduced the new Vexcalibur Exotic glaive through a secret //NODE.OVRD.AVALON// Exotic mission. This Exotic quest is followed by more quests, which add new abilities to Vexcalibur that help you discover secrets throughout //NODE.OVRD.AVALON//.

Last week, completing the Vexcalibur: Authorization Override quest allowed players to walk through Vex barriers and acquire another version of the weapon's Intrinsic Perk by accessing secret nodes. If you're looking to complete the Season of Defiance Title, you'll have to complete all three Override quests to get the Crtl-Alt-Complete Triumph.

Players can grab the second quest, called Vexcalibur: Expert Authorization Override, from the HELM.

It's best to do this in a Lost Sector like The Orrery on Nessus or the Thrilladrome on Neomuna to defeat Vex enemies quickly. You can also launch into the Garden of Salvation raid. Then, equip the new Expert Authorization Override mod on Vexcalibur.

You'll then have to complete the //NODE.OVRD.AVALON// mission again, and if you haven't done any of the Data Retrieval secrets in the Exotic mission--like the Data Retrieval: Substrate one that gets you the Intrinsic Perk--the quest will ask you to solve a mystery. After you complete the mission, head back to the HELM to grab your reward.

However, there are still other mysteries left to solve.

There is a large shaft near the beginning of the mission, right before you jump into the Vex Radiolaria. When jumping down the shaft, there are smaller platforms along the sides of the walls and one of those platforms has a green data node that you can
