The Aurora Blazer is a Hardmode flamethrower that drops from Astrum Aureus. It fires an erratic astral flame that travels quickly in a star shaped pattern that changes direction after travelling for 70 frames, or 32.8125 tiles, damaging enemies and inflicting the Astral Infection debuff. Once completing its path, it will return to the player. There is no limit to how many astral flames can be active at once.
Its best modifier is Unreal.
