Happened while friend was throwing damage bombs. awesome, please add the blocks, but ya its a glitch. Report sent in game (not me) happened on ps4
Edit: we have it on stream. will add video later when have clip
Edit 2: Added few extra pics of game tearing, bombed holes that look like stretched roads
Idea: Combine elemental fusion, refined rift, blink, and Umbris to craft a prismatic shard. These prismatic shards combined with the varying rocks could give us the rainbow rocks you see.
