I managed to kill enough creepers while fighting the brain of Cthulhu that I was able to make the pickaxe and mine hellstone, I now have full molten armor, a molten pickaxe, a volcano, and an imp staff to deal with weaker enemies.
I've also made the terraspark boots but still don't have the tally counter so I can't craft the cell phone yet. HOWEVER I do have the magic and demon conches so I can upgrade it into the shell phone when I craft it
I'm currently trying to defeat queen bee but haven't had any luck. If I defeat her the witch doctor can move in and I can make flasks of fire and flasks of poison, he'll be even more helpful in hardmode because I can make ichor flasks which lower enemy defense.
As the image implies I'm now fishing for a better alternative to healing potions, although honey bottles give a regeneration buff they won't be very helpful if you're fighting queen bee and getting hit by 20 projectiles at once
