And one more thing: if they ever catch you extremely unprepared, try saving and exiting Terraria IMMEDIATLY after their natural spawn message. There is a glitch that if you do that, they won't spawn. But that might've been fixed. And if you choose to fight the twins in the boss house, whatever you do - do not go to the opposite side of the house while Spazmatism is shooting his Cursed Flames. Say you're fighting Spazmatism in his second form - instead of a giant creepy eyeball he's a giant creepy eyeball version of Pacman with really, really bad breath. Spazmatism's on the left of you're house, and you go to the far right side of your house. Since both Twins can go through blocks, he'll follow you into your house and spew flames at you until you move enough to the left where he's back outside. And Retinazer is kind of like a sniper in his second form - in his first form he'll be charging you just like Spazmatism, but once he changes he keeps his distance. He'll try to shoot you from above - but if you have a roof or any blocks above you, he won't shoot. Neither of the twins will shoot you from a distance if they don't have a clear line of sight. After a while, Retinazer will try to shoot you from the side. That's usually when I charge outside and we have a five-second shoot-out. Then he moves back above, I go inside to get health potions. This technique takes almost all night, though. If the moon is going down and you only have one Twin left with very low health (preferably Retinazer) and your health is almost full, charge outside and fly up and around him with wings or one of the Rocket Boots combinations and shoot him with a bow or the Minishark. Besides, if the night's almost over and you're doing fine, what do you have to lose? And if you plan on using a summoning item to make them appear, make sure you haven't gotten their natural spawn message. Because if you summon them along with their natural appearance, you'll be fighting the Quadrupelets instead of the Twins. Two Retinazers, two Spazmatisms, and all four are connected to each other. Talk about a terrible night!
