Blazing Core

The Blazing Core is a post-Moon Lord Expert Mode-exclusive accessory obtained from Providence, the Profaned Goddess's Treasure Bag. While equipped, it increases the player's damage reduction by 10%. If the player is hit by an enemy, a miniature sun is created at the player's location for ten seconds that sucks enemies towards it, deals damage, and inflicts the Holy Flames debuff for three seconds. Only one sun can be active at a time.
