Psion Codewardens

'''Psion Codewardens''' are Major-rank Psions of the Psion Conclave, led by Qabix, Insurgent. They wear golden armor, carry Slug Shotguns and are protected by immunity shields. They first appeared in Season of the Risen.

Vox Obscura

In the Vox Obscura exotic mission, three Codewardens guard the control room, one in each of the left, center and right rooms of the flame-trap hallway. Each room also holds a Psion Commander, an Unstoppable Champion and fodder enemies. All three Codewardens must be defeated before the final boss area can be reached, and a Codewarden's death opens its terminal. Reported details of which enemy holds the codes differ between guides.

Shields

Nearby Psion Commanders generate the Codewardens' immunity shields. Guides describe breaking the shield by running up to the Psion Commander and meleeing it. Vox Obscura has rotated in and out of the game, so check its current availability.
