The Bloodflare Core is a post-Moon Lordaccessory exclusive to Expert Mode. It is obtained from the Ravager's Treasure Bag after defeating Providence, the Profaned Goddess. While equipped, all damage taken will temporarily reduce the player's defense. The amount of defense lost depends on how much damage was taken up to 50% of the player's max defense. Over time, defense will regenerate at 40 defense points per second. Each time the player regains a defense point, they are healed for 1 HP.
This accessory pairs well with Melee focused builds as melee armor sets tend to have the highest defense stats out of other builds.
While intended to be obtained from fighting the Ravager after it has been buffed, the item can alternatively be obtained alongside a wealth of crafting materials by defeating Ravager before Providence, storing the bag, and then opening it after defeating Providence. This allows a player to avoid the hassle of engaging the boosted Ravager, which can prove quite challenging even with the powerful gear obtained from Providence herself, especially in higher difficulties.
This accessory previously tailored to low defense builds before being reworked into the opposite.
