Nebulous Core

The Nebulous Core is a post-Moon Lord, Expert Mode-exclusive accessory that is obtained from the Treasure Bag dropped by The Devourer of Gods. It grants the player 12% increased damage and summons floating nebula stars around the player, just like the Spore Sac, that deal 1500 damage. It also grants the player a 10% chance to survive a lethal attack, healing the player for 100 HP when the effect triggers.
