The official support is provided here.

This is the re-implementation of "Engram" plugin featured in SSundee's Faction Series Youtube video:

A player can be given an engram, which encodes the chance to win some special goodies. (You can use a number of different ways to give out the engram such as crates, lucky mining, donation rewards, etc)

Once the user gets the engram, s/he will hand it over to the EngramNPC, which will decipher your engram for you, and find out and give you the special item/rewards!

The server owners can define many different tiers of engrams, each of which encodes different special items (or commands to be executed) with their own chance of successfully obtaining).
