Ancient Rimes, colloquially known as Rimed Ice, are chunks of odd, glowing ice that cannot be melted using Pyro DMG. To break them, the player must use the imbuement effect of Scarlet Quartz. When broken, Ancient Rimes may reveal chests, Crimson Agates, or other objects or items. They are typically found in Dragonspine.
The Ice Shards featured in Dragonspine quests are more powerful Ancient Rimes, requiring three attacks using different Scarlet Quartz to destroy them.
