Vigorsilk should be removed, as, for all intents and purposes in terms of balancing, it is easier to simply use Vigor Protein in 3 times the amount of Vigorsilk used in each recipe.
The boots shouldn´t use Leather, as it is Corruption-exclusive, while the headgear shouldn´t use glass.
The Pyrantula should drop Meteorite Bars, as it is likely that the player to have run out of Shadow Orbs/Crimson Hearts at that point.
Alternatively, Pyrantula just drops Vigorsilk in adjusted quantities.
I think Hellstone Bars would make more sense, personally, as they're much more hell-themed.
