The Astral Bulwark was a Hardmode, Expert Mode-exclusive accessory obtained from the Treasure Bag dropped by Astrum Deus, which caused five stars to drop from the sky when the player is hit. It also granted immunity to the Astral Infection debuff, which is inflicted by enemies in the Astral Infection biome.
