User blog:Huleyn162/Can't solo any of the hardcore bosses!!!

My main problem is with the twins,(I cant also beat skeletron prime and The destroyer, so don't ask me to make any of those special soul weapons/armors.) i can't even find the lenses required to make the Mechanical eye. Most of my surface world is corrupted/hollowed. And wandering eyes don't spawn because of this, is there any way to get lenses?

I have a full set of adamantite equipment (including armor, i have the adamantite helmet as the headgear.), and all of them has the Demonic prefix.

I have Angel wings, Spectre boots, Star cloak, obsidian horseshoe as accessories.

400 health, 200 mana.

I've got a proper arena.

I have that famous anti-Twins weapon, Crystal storm. It has no effect though.

What am i supposed to do? I barely defeated Wall of flesh (After 8 tries), but these guys are just impossible. And i can't ask my friends for help, they play terraria too, but they are n00bs and the most skilled of them has molten equipment.
