Reliquaries are available for sale from the Grook peddler in Enorian. These are useful against Nazedha squads, being as they grant players the unique ability to afflict and hinder Nazedha mobiles. Below is a brief explanation of how they work:

TOUCH RELIQUARY - if you are a member of a Divine Order, this will empower the reliquary with your God's Divine essence. A given reliquary can store up to three different types of essence.
TURN RELIQUARY - this will allow you to switch between which essence the reliquary will hit with.
PULL RELIQUARY - empties all Divine essence out of the reliquary.
POINT RELIQUARY AT <target> - unleash Divine power on any Nazedha squad unit or Nazedha band. Note that reliquaries function differently against squads and bands.
SHAKE RELIQUARY - see which essences a reliquary contains.

There is, at present, a small bug in which a reliquary will fill with the same essence twice if touched repeatedly, and this will count against the limit. This has not been fixed, but is easily averted by careful double-checking, and, if all else fails, emptying the reliquary.
