Keltham now has an enormous quantity of Resist Energy (Acid) spells! And a couple of Protection from Energy (acid) spells! And some of the cheaper raw materials and reagents he's requested have arrived! Today is an Acid Day!
Keltham is going to experiment with regularizing the reactions using Prestidigitation, including more arcane endeavors to modify stuff like the binding forces of outermost electron orbitals, or more mundane attempts to Prestidigate more precisely adjusted exact temperatures inside a reaction vessel, though he's improvised some attempted means of measuring temperatures inside pressurized boiling acid containers - haha oops that sure exploded!
Ione maybe did have a point about having some appropriate spells up. That would have been a lot more painful and possibly a lot harder to heal if if it hadn't just been the boiling-liquid damage he took there. Resist Energy (Fire) should work to prevent a repeat, right?
Back to figuring out how to precisely regulate the steps of acid manufacturing and purification using Prestidigitation!
