Gear Review
Mercurial is the most powerful set in Raid, as of 2026, having displayed Stone Skin as the set to build around and with. The set shows its true power with 9 pieces, providing a regenerative Total Guard stack on every turn. While the stats favor Support champions, this has found use with champions of all types. This set can be used in all areas of the game, with stats that make it more versatile than Stone Skin. Keep exceptional rare pieces and farm Grim Forest often to collect enough great pieces.
