Decoder

Decoder is an Aurelian Event found in Undercroft and Repository of Knowledge Expeditions. Encoded Tracers from the Tracer event can be brought to Decoder stations to unlock the data within.

Overview

The event is located in the Radiant Scriptorum, a courtyard with stained glass and three decoder devices. In the center of the room is a burning light, which activates the event. The Decoder event has two variants:

Tracer Decoding

The courtyard will be empty, and the decoder devices will be opened, allowing up to three Encoded Tracers to be set into them. After at least one tracer has been set, the light in the center can be interacted with to start the decoding process. During this process, Codex Initiates, Codex Monks, and Codex Sages will appear to defend the decoders. The ambush ends with a fight against the Cryptographer, who must be defeated to complete the event.

Third Keeper

The decoder devices will be closed, and the Third Keeper stands next to the light in the center. Defeating the Third Keeper will complete the event and open the decoders.

Rewards

Random Data Fragments will be rewarded, with the number correlating with the number of tracers placed in the devices. For the Third Keeper variant, three fragments will always be rewarded. The data fragments are used in the Facsimile event.
