DLC dungeons are considered a fallback event, in case trials do not happen.
For the inexperienced, it is the daily veteran DLC pledge; for the experienced, it can be any veteran DLC dungeon done for HM progression and achievement runs.
For the inexperienced, the idea is to clear the dungeon; for the experienced, the idea is to progress in HM/achievement runs.
Event doesn't have specific time: guild members can group up and go in any time during the day. In case of cancelled trial, we will try to do a matchmaking. If neither of these scenarios are valid, the default event time is 8:30pm CET/CEST.
Both Adeptus ranks, please signup showing your interest in the event, in general.
