First appearing in Koudelka, it can be gained by not fighting Charlotte. It merely increases the stats of whichever character has it equipped. In Shadow Hearts, since all Fusions cost a large chunk of SP to use, the Flare Brooch decreases the SP cost to fuse by 20%. In Shadow Hearts Covenant onwards, it simply halves the SP cost for maintaining Fusion form per turn. With the additions of characters that can fuse of become superhuman like Kurando and Johnny, the second and third games only have two Flare Brooches in the game world.
