Okay, yeah, pretty obvious power disparity here. All three times I tried to kill the twins, I got absolutely wrecked, and my best attempt only got one of them to half health.
So I decide to take on the Destroyer, get some Souls of Might, and get a megashark. I prep heavily for it, half a dozen potions, soup, a very large arena, upgraded my Mythril armor to Adamantite, made wings, pulled out the last of my stars, upgraded my star cannon, made a few thousand crystal bullets for my Clockwork AR, got two stacks of health potions, and summoned it... I killed it in about a minute, without using a single health potion. I quickly made two more mechanical worms and killed it twice more that night. I got enough souls from it for a megashark and Excalibur, with 25 left over.
Yeah. -__-
So my basic expectation of the future is: Farm it some more, gather more souls, farm Optimus Prime for a bit, get a flamethrower, attack the Twins with the best endgame equipment, barring Hallowed armor, and still get stomped into the ground.
So if they really had to balance the Twins for multiplayer gameplay, why the hell didn't they think "oh, maybe there are people who can't or won't play multiplayer, and people who don't want to convince a couple friends every time they want to kill a boss" and set them up so they scaled, say, health, based on how many players above 200hp are in the game, similar to the Goblin Siege? Because the destroyer isn't nearly as hard as I expected, and I expect that Skelly Prime won't be, either, but the Twins are blatantly overpowered for a solo fight, considering that they're supposed to be the upgrade to the most basic boss. It even seems like they have much higher defense than the Destroyer, considering how fast it went down, despite having four times the health of one of the Twins, who took my life for just 12000 damage on a straight line.
