The jungle temple is now just ruins on the jungle surface, you can craft a power cell here with gold/platinum with stars, after this, plantera bulbs will spawn, she will no longer be enranged on the surface to make it less harsh considering she is the second boss now, afterwards, you can fight the mechs, which look a bit more makeshift now, the twins no longer have a second form and skeletron prime has 2 arms now, destroyer could function like the eater of worlds now, (this can be interpreted as the mechanic making bosses to practice on before fighting the real deal in hardmode), after that, you can kill queen slime, who now drops hallowed bars, which are now nerfed, you can use the pickaxe axe/drax to mine hellstone, now to kill the wall of flesh, now you kill skeletron, queen bee, the eater/brain (shadow and crimson gear has been buffed along with dungeon loot) and then the cultist at the dungeon, who is trying to summon the eye of cthulhu, the final boss, with a new death ray attack and now shoots lasers, when in his second phase, he spawns 3 servants of cthulhu, that are now invisible and shoot lasers.
