Looking around on the PTS today, I noticed a new tab under “Raids” labeled as Primeval Feast that contains achievements that total up to 180 achievement points. Looking through them it looks like this new raid is a mixture of previous bosses we’ve encountered: Hylas; Altha, Ember Isle’s Life Event boss and Atrophinius from Realm of the Fae and Runic Descent. These two alone along with the wording lead me to believe that this instance will be a life-based raid.
My guess for it being a 10 man is only based solely on the fact that the amount of achievement points are pretty much in line with the other 10 mans: 200 (Original) for Guilded Prophecy, 220 (Original) for Drowned Halls, 200 (Original) for Rise of the Phoenix.
The achievements on the PTS right now are:
- 40 Days and 40 Knives
Kill Forty Banetouched minions before destroying the Life Anchors.
- Anchor Man
Destroy both Life Anchors within five minutes after Hylas dies.
