Hi, sorry for my broken english… I just wanted to share something I found in the 2nd Dark Aether Rift.
Inside the stadium area, I found 3 pieces of what you call "Element 115" (I'm not deep into "Aether" lore). These "rocks" are emitting the same sound of the "offer unatunned relic" rocks, but if you come closer, a "square" prompt will appear with no text. Press it and the rock will disappear. After you found the last one, the song "115" (instrumental versión) will start playing…
Maybe a good time to play again inside rifts of past seasons? And to check for other hidden stuff 🙂
I'm sharing the places where I found the rocks… Or you may follows the sound of the rocks.
