what is in the abyssal ruins
Edit Page Last Edit: 4 years ago. Abyssal Ruins is an underwater ruin in North Eastern Unova. It can only be reached by using HM06 - Dive in Undella Bay. The entire ruin is like an underwater maze. Swim around and pick up Relic Items that can be sold to a maniac in Undella Town for a high price. You can also find Plates for Arceus hidden around here.
