Terraria 1.4 - Stardust Guardian vs All Bosses
Stardust Guardian was upgraded in Terraria: Journey's End and now he attacks enemies without activation and he deals much more damage. You just need to wear Stardust Armor. In this video I defeated almost all bosses in Normal Mode with Stardust Guardian only. In this video you can also find out how to summon Empress of Light and Queen Slime.
