A new 265MB update has arrived on the Public Test Shard (“PTS”) for 22nd May 2014. The main new change is the addition of some Nightmare Coast Dungeon achieves. This is likely a 3.0 dungeon. It is found on the PTS under Achievements -> Dungeon.
This doesn’t seem to be all the quests and some are incomplete – like the ‘Nightmare Coast’ achieve for standard difficulty level that only has one boss “Lord Arak” included.
The achievements do provide insight into at least some of the bosses of the instance:
- Dalrakk the Shadowlord – Seems Death-themed.
- Shade of Akylios – Given the name plus the ‘Squidn’t We Already Kill Him?’ achievement name, this is likely Akylios again but in a Dungeon-level-difficulty version. The ‘Tentafool’ achievement suggests that this fight we have tentacles just like the raid version.
- Hydal Ithral – Water-based boss with a Nightmare Mechanic.
- Lord Arak – Water-based boss. Probably the first one attempting to summon Akylios or awaken the Akvan.
The Nightmare Coast dungeon is the first achievement sub-category with actual achievements that are up on the PTS (and not datamined). The PTS also has Nightmare Rifts, Tarken Glacier, Draumheim and Goboro Reef sub-categories although none of them have any achievements added.
Could this be a sign of Trion beginning to open up the PTS to more 3.0 content teasers?
Daglar has mentioned before that initial closed beta testing would have a very small handful of external players involved by the end of May 2014 [r]. As such these achievements may have been added in for their benefit – to test out the dungeon as well as to make sure the achievements are working.
In the mean-time, we’ll continue to keep an eye out on future PTS updates!

A 5 man version of Akylios?!?!? Hell yea! I’ve been waiting for this for years. This dungeon seems really awesome, I’d really like if they introduced even more achievements for 5 mans. I feel like 1.0 dungeon conqueror was a big thing where as with 2.0 dungeon feats and achieves were shrugged over.
Yea, I’m definitely interested in seeing how it goes. Was a shame they didn’t expand on the HK Chronicle to include some of the other bosses. Also agree with the achieves – felt it with the PA XP Crystals as zone category achieve rewards. Kind of lackluster.
