Since I've never seen Basil carry any Cobalt line, Aegis line, Valiance line, or Calibur line recipes, I think it bears mentioning that he stocks the Nitronome recipe from time to time. Kinda sad when you're looking for a specific 5 star recipe and you just have that Nitronome recipe down at the bottom glaring at you.
Kozma would like a word with you about that. You're encroaching on her territory!
He's always carried all of the blast bomb lines, as far as I know.
