Armor box

Armor boxes are boxes that are shared between missions, and can be located either in the clear boxes or found mid-mission. They have a chance of dropping specific Line Shields based on the mission rank. Due to them being scattered around they can sometimes drop materials or Line Shields that feel out of place - there is a chance of getting Meta-materials out of one of these boxes in Sacred Stream, for instance.

In the event you find a Line Shield or synthesis board that is not listed on a mission's clear rewards, if it appears in the lists below, it is the product of an Armor box.

Armor boxes can drop the following items:
